On June 6, 2011, the Web site reported the following response times to Asia, in milliseconds:

61 32 50 73 51 42 55

65 59 57 76 77 67 71

Assume the population distribution is approximately normal and using level of significance ? = 0.05, test whether the population mean response time is less than 60 milliseconds.

For each of the following two-samples t-tests (problems 1-6): (a) Determine if a F test for the ratio of two variances is appropriate to calculate for the context. If it is appropriate, conduct the analysis and report the result. Include what statistical conclusion you should draw from the analysis (i.e., whether you should conduct a pooled-variance t-test or an unequal-variances t-test). (b) Identify the most appropriate t-test to conduct for the situation/data given. Don’t forget to consider if the context...
