A random sample of n1 = 52 men and a random sample of n2 = 48 women were chosen to wear a pedometer for a day. The men’s pedometers reported that they took an average of 8,342 steps per day, with a standard deviation of s1 = 371 steps. The women’s pedometers reported that they took an average of 8,539 steps per day, with a standard deviation of s2 = 214 steps. We want to test whether men and women...

Assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations. a. Construct a 98% confidence interval for the difference between the mean speeds of cars driven by all men and all women on this highway. b. Test at a 1% significance level whether the mean speed of cars driven by all men drivers on this highway is higher than that of cars...

Do Men Talk Less Than Women? The accompanying table gives results from a study of the words spoken in a day by men and women, and the original data are in Data Set 17 in Appendix B (based on “Are Women Really More Talkative Than Men?” by Mehl et al., Science, Vol. 317, No. 5834). Use a 0.10 significance level to test the claim that the mean number of words spoken in a day by men is less than that...
