Suppose we toss a fair coin three times and denote outcomes in the sample space S by listing, in order, the observed Heads (h) and Tails (t). (a) Let X be the random variable counting the number of Heads, and Y be the random variable counting the number of Tails. (i) State the range of the functions X and Y , i.e., list the values they can take. (ii) Evaluate X(hht) and Y (hht). (b) Let Z be another random variable defined as Z = max{X, Y }. (i) State the range of the function Z, i.e., list the values it can take. (ii) Evaluate Z(hht). (c) Determine the probability that we see more Tails than Heads.

Executives of a supermarket chain are interested in the amount of time that customers spend in the stores during shopping trips. The mean shopping time, μ, spent by customers at the supermarkets has been reported to be 40 minutes, but executives have good reason to believe that µ is different from 40 minutes. The executives hire a statistical consultant and ask her to perform a statistical test. To perform her statistical test, the consultant collects a random sample of shopping times at the supermarkets. She computes the mean of these times to be 36 minutes and the standard deviation of the times to be 15 minutes. Based on this information, complete the parts below. (a) What are the null hypothesis and the alternative hypothesis H₁ that should be used for the test? Ho H₁:0 (b) Suppose that the consultant decides to reject the null hypothesis. What sort of error might she be making? (Choose one) (c) Suppose the true mean shopping time spent by customers at the supermarkets is 33…

A sample of 8 people participated in a low calorie weight loss program for 16 weeks. Each of the participants had their weight (in pounds) recorded before they started the program and after they finished the program. The following results were obtained. Estimate the mean amount of weight a person participating in this low calorie weight loss program can expect to lose at the end of 16 weeks. Assume that the amount of weight people lose after 16 weeks participating in this low calorie weight loss program reasonably follows a normal distribution. Express the estimate both symbolically and verbally.
A city planner is comparing traffic patterns at two different intersections. He randomly selects 12 times between 6 am and 10 pm, and he and his assistant count the number of cars passing through each intersection during the 10-minute interval that begins at that time. He plans to test the hypothesis that the mean difference in the number of cars passing through the two intersections during each of those 12 times intervals is 0. Which of the following is appropriate test of the city planner's hypothesis? (a) Two-proportion z-test (b) Two-sample z-test for a difference in means (c) Two proportion t-test (d) Paired t-test for a mean difference (e) Two-sample t-test for a difference in means
