Determine the null hypothesis, Ho, and the alternative hypothesis, H1. Let females be population 1 and males be population 2. Ho2 P1'l'2 ll "'12 P1'P2 TI (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 pvalue is V the chosen value of a, 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
