RES/342 Week One: One Sample Hypothesis Testing
Objective: Identify the formal hypothesis testing process.
1. Hypothesis testing is the statistical process of analyzing sample data
by using probability theory to determine whether a stated hypothesis is
reasonable. For a particular test, a business owner wanted to know
whether changes in a production practice resulted in significant
timesaving in manufacturing the company’s product. The business
owner develops the alternative hypothesis that the population mean after
the change is less than the population mean before the change. To test
this question,
a. 0 a two-tailed test should be applied
b. 0 a left-tailed test should be applied is the correct answer
c. 0 a right-tailed test should be applied
d. 0 more information is required to make a decision
Objective: Perform a hypothesis test of one proportion.
2. The Roman Senate has become concerned about the loyalty of the
army in Gaul commanded by Julius Caesar. They claim that, of the
80,000 men in the army, at least 28,000 are foreign barbarians. Caesar
believes that there are fewer barbarians, so the Senate should not worry.
He polls a legion of 1,000 men and finds that 340 of them are
barbarians. Assume the value of the test statistic is -0.70. Calculate the
p-value for this test using Microsoft® Excel®.
a. 0 =NORMSDIST(-0.7) yes
b. 0 =TDIST(-0.70,999,1)
c. 0 =2*(NORMSDIST(-0.7))
d. 0 =TDIST(0.7,999,2)
Objective: Perform a hypothesis test of one population mean using the
standard normal distribution.
3. The manager of a fast food restaurant is concerned that it is taking
too much time for drive-thru customers to be processed. The time period
of concern is from when a customer’s order is placed to when he or she
receives his or her food. An acceptable amount of time for this process
has been 1.3 minutes. To address this concern, a sample test was
conducted. A sample of 24 random customers was taken and it was
determined that the processing time was 1.41 minutes, with a standard
deviation of 0.12 minutes. Is this difference significant? At the 0.05
significance level, which of these statements is correct?
a. 0 The critical value is ±1.96.
b. 0 The critical value is 1.714. yes
c. 0 The test statistic is 0.92.
d. 0 The test statistic is 4.58.
Objective: Interpret the results of hypothesis tests.
4. The mean length of a small counterbalance bar is 43 millimeters.
There is concern that the adjustments of the machine producing the bars
have changed. Test the claim, at the 0.02 level, that there has been no
change in the mean length. The alternate hypothesis is that there has
been a change. Twelve bars (n = 12) were selected at random and their
lengths were recorded. The lengths are, in millimeters, 42, 39, 42, 45,
43, 40, 39, 41, 40, 42, 43, and 42. The mean of the sample is 41.5 and
the standard deviation is 1.784. Computed, t equals – 2.913. Has there
been a statistically significant change in the mean length of the bars?
a. 0 A larger test sample is needed.
b. 0 Yes, because the computed t lies in the area beyond the critical
value correct
c. 0 No, because the information given is not complete
d. 0 No, because the computed t lies in the area to the right of –2.718

RES/342 Week Two: Two or More Sample Hypothesis Testing
Objective: Apply hypothesis testing to different populations and samples
in business research situations.
5. In conducting research that looks at differences in populations,
samples are used for numerous reasons. Using entire populations in a
test is difficult, so various sampling techniques are applied. In situations
in which the population variance is unknown, the Student t distribution
is often used. To use this distribution, certain assumptions must be
made. Which of the following statements is not correct?
a. 0 The t distribution is a family of distributions.
b. 0 It is a symmetrical, mound shape distribution.
c. 0 It is a continuous distribution.
d. 0 It has less spread than the standard normal distribution.
Objective: Perform a hypothesis test of two population means using the
standard normal distribution.
6. The Ohio State Patrol has identified eight intersections in Clermont
County of high risk, due to the number of accidents. To address these
concerns, the state patrol wants to make some changes in the traffic light
patterns at these intersections. A proposal was developed to do a 4-
month test of these changes at the eight intersections to see whether a
significant decrease in accidents occurred. The number of accidents 2
months before the modifications at the eight intersections was 57 and the
number of accidents 2 months after the modification was 37. To conduct
the test, the .01 significance level was selected. The test statistic was -
2.415. What would be the critical value for the test decision to be made?
a. 0 2.624
b. 0 -2.998
c. 0 2.947
d. 0 2.602
Objective: Perform a hypothesis test of two proportions.
7. Historically, single-income households or individuals have made up
about 27 percent of the housing market. A sample of 80 recent
mortgages indicated that 24 single-income families or individuals
purchased a new home. Has there been a change in this historical belief?
a. 0 The market has not changed.
b. 0 The market is generally difficult to predict due to the changing
economy.
c. 0 The market has changed.
d. 0 More information is needed to make any statement.
Objective: Determine when to use an ANOVA for managerial decisions.
8. A business owner is trying to decide between three different ads for
the yellow pages. The ads are of different sizes and costs. The owner
wants to get the best deal possible to save money, but wants to
effectively reach potential customers. The question is whether there is a
significant difference between the three different ads in their
effectiveness in reaching customers. To make a more informed decision,
the manager should choose which statistical test?
a. 0 Linear regression correlation
b. 0 Goodness-of-fit test
c. 0 Simple linear regression
d. 0 Analysis of variance (ANOVA)
Objective: Perform an ANOVA.
9. On-Time, a package delivery company, just purchased 14 new trucks
from three different companies. Five trucks were purchased from
manufacturer A, four from B, and five from C. The cost of maintaining
each truck was recorded. On-Time used an ANOVA to test whether the
mean maintenance costs of the trucks from each manufacturer were
equal. To make the decision regarding this hypothesis, a critical value is
required. What would be the critical value for the decision when the 0.01
significance level is used?
a. 0 6.22
b. 0 7.56
c. 0 7.21
d. 0 6.93

  • 6. Prepare to take a quiz on topics covered in previous weeks. RES/342 Week One: One Sample Hypothesis Testing Objective: Identify the formal hypothesis testing process. 1. Hypothesis testing is the statistical process of analyzing sample data by using probability theory to determine whether a stated hypothesis is reasonable. For a particular test, a business owner wanted to know whether changes in a production practice resulted in significant timesaving in manufacturing the company’s product. The business owner develops the alternative hypothesis that the population mean after
  • 7. the change is less than the population mean before the change. To test this question, a. 0 a two-tailed test should be applied b. 0 a left-tailed test should be applied is the correct answer c. 0 a right-tailed test should be applied d. 0 more information is required to make a decision Objective: Perform a hypothesis test of one proportion. 2. The Roman Senate has become concerned about the loyalty of the army in Gaul commanded by Julius Caesar. They claim that, of the 80,000 men in the army, at least 28,000 are foreign barbarians. Caesar believes that there are fewer barbarians, so the Senate should not worry. He polls a legion of 1,000 men and finds that 340 of them are
  • 8. barbarians. Assume the value of the test statistic is -0.70. Calculate the p-value for this test using Microsoft® Excel®. a. 0 =NORMSDIST(-0.7) yes b. 0 =TDIST(-0.70,999,1) c. 0 =2*(NORMSDIST(-0.7)) d. 0 =TDIST(0.7,999,2) Objective: Perform a hypothesis test of one population mean using the standard normal distribution. 3. The manager of a fast food restaurant is concerned that it is taking too much time for drive-thru customers to be processed. The time period of concern is from when a customer’s order is placed to when he or she receives his or her food. An acceptable amount of time for this process has been 1.3 minutes. To address this concern, a sample test was
  • 9. conducted. A sample of 24 random customers was taken and it was determined that the processing time was 1.41 minutes, with a standard deviation of 0.12 minutes. Is this difference significant? At the 0.05 significance level, which of these statements is correct? a. 0 The critical value is ±1.96. b. 0 The critical value is 1.714. yes c. 0 The test statistic is 0.92. d. 0 The test statistic is 4.58. Objective: Interpret the results of hypothesis tests.
  • 10. 4. The mean length of a small counterbalance bar is 43 millimeters. There is concern that the adjustments of the machine producing the bars have changed. Test the claim, at the 0.02 level, that there has been no change in the mean length. The alternate hypothesis is that there has been a change. Twelve bars (n = 12) were selected at random and their lengths were recorded. The lengths are, in millimeters, 42, 39, 42, 45, 43, 40, 39, 41, 40, 42, 43, and 42. The mean of the sample is 41.5 and the standard deviation is 1.784. Computed, t equals – 2.913. Has there been a statistically significant change in the mean length of the bars? a. 0 A larger test sample is needed. b. 0 Yes, because the computed t lies in the area beyond the critical value correct c. 0 No, because the information given is not complete d. 0 No, because the computed t lies in the area to the right of –2.718 ************************************************

  • 20. 5. In conducting research that looks at differences in populations, samples are used for numerous reasons. Using entire populations in a test is difficult, so various sampling techniques are applied. In situations in which the population variance is unknown, the Student t distribution is often used. To use this distribution, certain assumptions must be made. Which of the following statements is not correct? a. 0 The t distribution is a family of distributions. b. 0 It is a symmetrical, mound shape distribution. c. 0 It is a continuous distribution. d. 0 It has less spread than the standard normal distribution. Objective: Perform a hypothesis test of two population means using the standard normal distribution.
  • 21. 6. The Ohio State Patrol has identified eight intersections in Clermont County of high risk, due to the number of accidents. To address these concerns, the state patrol wants to make some changes in the traffic light patterns at these intersections. A proposal was developed to do a 4- month test of these changes at the eight intersections to see whether a significant decrease in accidents occurred. The number of accidents 2 months before the modifications at the eight intersections was 57 and the number of accidents 2 months after the modification was 37. To conduct the test, the .01 significance level was selected. The test statistic was - 2.415. What would be the critical value for the test decision to be made? a. 0 2.624 b. 0 -2.998 c. 0 2.947 d. 0 2.602 Objective: Perform a hypothesis test of two proportions.
  • 22. 7. Historically, single-income households or individuals have made up about 27 percent of the housing market.

The question is whether there is a significant difference between the three different ads in their effectiveness in reaching customers. To make a more informed decision, the manager should choose which statistical test? a. 0 Linear regression correlation b. 0 Goodness-of-fit test c. 0 Simple linear regression d. 0 Analysis of variance (ANOVA)
  • 24. Objective: Perform an ANOVA. 9. On-Time, a package delivery company, just purchased 14 new trucks from three different companies. Five trucks were purchased from manufacturer A, four from B, and five from C. The cost of maintaining each truck was recorded. On-Time used an ANOVA to test whether the mean maintenance costs of the trucks from each manufacturer were equal. To make the decision regarding this hypothesis, a critical value is required. What would be the critical value for the decision when the 0.01 significance level is used? a. 0 6.22 b. 0 7.56 c. 0 7.21 d. 0 6.93
