Is the value of the chi-square statistically significant at the 0.05
level?
2.
Write a paragraph summarizing the results of the analysis in
Exercise 1.

7. Using StatCrunch, calculate the chi-square statistic and degrees
of freedom for the following set of data for 180 people
undergoing a knee replacement treatment with a drug
supplement:
Treatment with drug X Treatment without Drug X

8. 180
Is the value of the chi-square statistically significant at the 0.05
level?
4.
Write a paragraph summarizing the results of the analysis in
Exercise 3.
5.
Given each of the following circumstances, determine whether
the calculated values of chi-square are statistically significant:
a. χ2 = 3.02, df = 1, α = 0.05
b. χ2 = 8.09, df = 2, α = 0.05
c. χ2 = 10.67, df = 3, α = 0.01
d. χ2 = 9.88, df = 2, α = 0.01
6.
Match each of the nonparametric tests in Column A with its
parametric counterpart in Column B
A. Nonparametric Test
B. Parametric Test
1. Mann-Whitney U-test

9. a. Paired t-test
2. Friedman test
b. One-way ANOVA
3. Kruskall-Wallis test
c. Independent groups t-test
4. Wilcoxon signed-ranks test
d. Repeated measures ANOVA
7.
Using the information provided, indicate which statistical test
you think should be used for each of the following situations:
a. Independent variable: normal birth weight vs. low birth
weight infants; dependent variable: breathing rate (in breaths
per minute).
b. Independent variable: time of measurement of same patient
(before, during, and after surgery); dependent variable: heart
rate.
c. Independent variable: time of measurement (before, during,
and after intervention); dependent variable: did vs did not
exercise regularly.
d. Independent variable: infertility treatment A vs infertility

10. treatment B vs control condition; dependent variable: did vs did
not become pregnant.
8. The relationship between cigarette smoking and major
depressive disorder has been studied for decades. In the doc
sharing area of the course, you will find an excel spreadsheet of
data from a study on smoking and depression by the St Louis
Epidemiologic Catchment Area Survey of the National Institute
of Mental Health. The file is labeled “Catchment Area Survey”.
Using this data set in StatCrunch, calculate the chi-square
statistic and degrees of freedom for the items “smoker” and a
measure of depression, “FeltDown”. Construct a contingency
table for this data as we did in week 1. Be sure to include and
label the row, column and total %’s as well as the expected
counts. Is the value of the chi-square statistically significant at
the 0.05 level? Any reason to use a correction to the chi-square
test here given your expected counts?
9.
Write a paragraph summarizing the results of the analysis in
Exercise 8. What can you conclude about smoking and
depression (“Feeling Down”) in this sample?
10. Below are three (a-c) sets of cells of 2 X 2 contingency
tables including the expected frequencies (Totals not included).
Identify which statistical procedure would be appropriate for
each, using the most conservative approach.
