The accompanying data gives the results of a survey on the number of hours spent online per week on a certain social networking website. Determine if the mean number of hours spent online per week is the same for males as it is for females. Assume that the population variances are unequal. Gender, Hours online/ week, Gender, Hours online/week Female 4 Male 7 Female 10 Male 15 Female 8 Male 5 Female 4 Male 3 Female 7 Male 5 Female 12 Male 5 Female 2 Male 10 Female 7 Male 4 Female 2 Male 5 Female 6 Male 9 Female 8 Male 6 Female 4 Male 3 Female 5 Male 6 Female 5 Female 9 Female 12 Female 1 Female 8 Female 1 Female 7 Is there sufficient evidence at the 0.05 level of significance that the mean number of hours spent online per week is the same for males as it is for females? Determine the null hypothesis, H Subscript 0, and the alternative hypothesis, H Subscript 1. Let females be population 1 and males be population 2. H Subscript 0: H Subscript 1: (Type integers or decimals. Do not round.) Compute the test statistic. ? Round to two decimal places as needed.) Find the p - value for the test. (Round to three decimal places as needed.) State the conclusion. The p- value is the chosen value of alpha, so_ the null hypothesis. There is_ evidence to conclude that the mean number of hours spent online per week for males is different than for females.

1 Female 7 Is there sufficient evidence at the 0.05 level of significance that the mean number of hours spent online per week is the same for males as it is for
females? Determine the null hypothesis, H Subscript 0, and the alternative hypothesis, H Subscript 1. Let females be population 1 and males be population 2. H
Subscript 0: H Subscript 1: (Type integers or decimals. Do not round.) Compute the test statistic. ? Round to two decimal places as needed.) Find the p - value
for the test. (Round to three decimal places as needed.) State the conclusion. The p - value is _ the chosen value of alpha, so _ the null hypothesis. There is _
evidence to conclude that the mean number of hours spent online per week for males is different than for females.
