Problem 2

A company is interested in knowing whether males and females differ in the amount of time they spend online. They ordered you to perform a study, and you reported that women spent a mean of 1,068 minutes per week online as compared to 1,398 minutes per week for men. The sample sizes were 100 each for women and men, and the population standard deviation for women was 50 minutes per week as compared to 75 minutes per week for men. You also know that α = 0.01.

What is your conclusion?

Select one:

a. There is not enough information for reaching a conclusion

b. There is no difference between men and women on time spent online

c. The time spent by men online is less than the time spent by women online

d. There is a significant difference between men and women on time spent online

1. You are interested in whether the average lifetime of Duracell AAA batteries is less than the average lifetime of Energizer AAA batteries. You lay out your hypotheses as follows: Null Hypothesis: μ1 ≥ μ2, Alternative Hypothesis: μ1 < μ2 (Duracell = Group 1, Energizer = Group 2). You perform an experiment on 20 randomly selected Duracell AAA batteries and 40 randomly selected Energizer AAA batteries and test them using a battery drainer. The Duracells had an average lifetime of...
