MA260.2.1 Statistical Analysis ILog Out Online Exam 6_06 Return to Assessment List Part 1 of 2 -30.0/ 50.0 Points Question 1 of 400.0/ 2.5 Points Jody checked the temperature 12 times on Monday, and the last digit of the temperature was odd six times more than it was even. On Tuesday, she checked it 18 times and the last digit was odd eight times more than it was even. Determine which series is closer to the 50/50 ratio of odd/even expected of such a series of temperature checks. A. The Monday series is closer because 1/6 is closer to 1/2 than is 1/8. B. The Monday series is closer because 6/12 is closer to 0.5 than is 8/18. C. The Tuesday series is closer because the 13/18 is closer to 0.5 than is 9/12. D. The series closest to the theoretical 50/50 cannot be determined without knowing the number of odds and evens in each series. Question 2 of 402.5/ 2.5 Points Joe dealt 20 cards from a standard 52-card deck, and the number of red cards exceeded the number of black cards by 8. He reshuffled the cards and dealt 30 cards. This time, the number of red cards exceeded the number of black cards by 10. Determine which deal is closer to the 50/50 ratio of red/black expected of fairly dealt hands from a fair deck and why. A. The first series is closer because 1/10 is farther from 1/2 than is 1/8. B. The series closer to the theoretical 50/50 cannot be determined unless the number of red and black cards for each deal is given. C. The second series is closer because 20/30 is closer to 1/2 than is 14/20. D. The first series is closer because the difference between red and black is smaller than the difference in the second series. Question 3 of 402.5/ 2.5 Points On a multiple choice test, each question has 6 possible answers. If you make a random guess on the first question, what is the probability that you are correct? A. 1/5 B. 1/6 C. 1/4 D. 2/5 Question 4 of 402.5/ 2.5 Points Suppose you have an extremely unfair die: The probability of a 6 is 3/8, and the probability of each other number is 1/8. If you toss the die 32 times, how many twos do you expect to see? A. 2 B. 4 C. 3 D. 5 Question 5 of 402.5/ 2.5 Points Suppose you buy 1 ticket for $1 out of a lottery of 1000 tickets where the prize for the one winning ticket is to be $500. What is your expected value? A. $0.00 B. −$0.40 C. −$1.00 D. −$0.50 Question 6 of 400.0/ 2.5 Points The distribution of B.A. degrees conferred by a local college is listed below, by major. Major Frequency English 2073 Mathematics 2164 Chemistry 318 Physics 856 Liberal Arts 1358 Business 1676 Engineering 868 9313 What is the probability that a randomly selected degree is not in Business? A. 0.7800 B. 0.8200 C. 0.8300 D. 0.9200 Question 7 of 402.5/ 2.5 Points The probability that Luis wi.
