According to a recent survey, women chat on their mobile phones more than do men. To determine if the same patterns also exist in colleges, Irina takes a random sample of 40 male students and 40 female students in her college. She finds that female students chatted for a sample average of 820 minutes per month, with a sample standard deviation of 160 minutes. Male students, on the other hand, chatted for a sample average of 760 minutes per month, with a sample standard deviation of 240 minutes. It is not reasonable to assume equal population variances. Do the same patterns appear to exist in college? Conduct an appropriate test to answer this question, using the .05 level of significance. Please complete all steps in the test process and please show all work.

Expert Solution

Independent samples T-test has been carried out for hypothesis testing. Following are the steps followed:

Thus, at 0.05 significance level, there is not enough evidence to support the claim that women chat on their mobile phones more than do men. In other words, at 0.05 significance level, there is not enough evidence to support the claim that the same patterns appear to exist in college.

According to a report by the American Cancer Society, more men than women smoke and twice as many smokers die prematurely than nonsmokers. In random samples of 200 males and 200 females, 62 of the males and 54 of the females were smokers. • Is there sufficient evidence to conclude that the proportion of males who smoke is greater than the proportion of females who smoke? α = .01 • Calculate the p-value associated with the test

She was given repair estimates that averaged $85, with a standard deviation of $28. Her friend John, taking the same set to another sample of 9 shops, was provided with an average estimate of $65, with a standard deviation of $21. Assuming normal populations with equal standard deviations,...
