Suppose we are interested in whether there is a difference between the median numbers of hours spent each week by men and woman watching television. Two random samples were taken: the numbers of hours taken by men and women watching television are shown below. You are about to test the null hypothesis that there is no difference in weekly television watching hours between men and woman. Men: 5 10 12 15; Women: 0 7 4 3 6 8

a) calculate the rank sum for the smaller sample;

b) calculate the z statistic to test the null hypothesis; (I don't know how to get m for this question so do I use a different formula?)

c) what is the p value according to the above test?

d) give the possible range for the rank sum for the smaller sample

We are interested in studying whether there is a difference in the time it takes for patients to recover after surgery for two given hospitals. A simple random sample of cardiac surgery patients were taken from each hospital. The results were summarized in the table below. It shows the hospital one attended (Hospital A vs Hospital B), and the average length of stay (measured in days) for patients after cardiac surgery. n Average Length of Stay (in days) Sample Standard...

We are interested in understanding if there is a difference between the consumption of personal training between two of our tapestry segments. Segment 1 uses personal training 6.3 times on average per year (n=1000). Segment 2 uses personal training 5.8 times on average per year (n=850). The standard deviation for segment 1 is 2.3 and for segment 2 is 3.2. Is this a significant difference? Why or why not? Assume we are looking for 99% significance.

Researchers are interested in whether there is a difference in happiness levels between people that live on the West Coast and people that live on the East Coast. A simple random sample of people were selected from each coast to take an assessment of their happiness. Scores on the happiness assessment range from 1-20. The happiness scores for the individuals assessed are below. East Coast Happiness Scores West Coast Happiness Scores 9.7, 18.8, 19.9, 10.1, 8.9, 15.0, 16.4, 10.1, 11.0,...

Suppose that we are interested to determine whether the mean unemployment duration in state A is different from the mean unemployment duration in state B. Suppose also we collect information from samples of unemployed workers from the two states and track the duration in weeks until they get employment. The following table summarizes the sample results and the population standard deviations State A State B Sample Size 64 81 Sample mean unemployment duration (in weeks) 20 23 Population standard deviation...

A university is interested in whether there's a difference between students who live on campus and students who live off campus with respect to absenteeism. Over one semester, researchers take random samples of on-campus and off-campus students and record the following number of classes each student misses. On-campus: (3, 4, 0, 6, 2, 1, 3, 3, 5, 2, 4, 4, 6, 5, 2) Off-campus: (6, 5, 2, 6, 2, 0, 7, 8, 1, 7, 2, 6, 5, 3, 2) a)...

.You are interested in determining whether there is a statistically significant difference between economics and political science majors in terms of their overall grade point average (GPA). You randomly sample 10 economics majors and 16 political science majors. You find that the average economist has a 3.0 GPA with a standard deviation of 0.4, and the average political scientist has a 3.4 GPA with a standard deviation of 0.3. Conduct a two-tailed hypothesis test using significance level α = 0.05....

Suppose we are interested in studying whether exposure to a pesticide increases the risk of prostate cancer. Assume that 20% of controls are exposed to the pesticide and we wish to detect an odds ratio of 2.7 from the exposure. Note that p2 = 0.2 and we need to calculate p1. How many cases and how many controls are needed in your case-control study?

We wish to test whether or not there is a difference between two of our production lines in terms of the defect rate. We examine 400 products on Line A and find that 40% are defective, whereas we examine 100 products on Line B and find that 20% are defective. What is the appropriate test statistic here?
