Is there sufficient evidence at the 0.01 level of significance that the average number of years of service is the same for males and females? Determine the null hypothesis, Ho, and the alternative hypothesis, H,. Let females be population 1 and males be population 2. Ho: Hy: (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 a, so the null hypothesis. There is evidence to conclude that the average number of years of service is different for males and females. b. Is there sufficient evidence at the 0.01 level of significance that the average years of undergraduate study is the same for males and females? Determine the null hypothesis, Ho, and the alternative hypothesis, H,. Let females be population 1 and males be population 2. Ho (Type integers or decimals. Do not round.) Compute the test statistic.State the COHCIUSIOn. The p-value is V the chosen value of a, so V the null hypothesis. There is ' evidence to conclude that the average number of years of sen/ice is different for males and females. b. Is there sufcient evidence at the 0.01 level of signicance that the average years of undergraduate study is the same for males and females? Determine the null hypothesis, Ho, and the alternative hypothesis, H1. Let females be population 1 and males be population 2. 238% (Type integers or decimals. Do not round.)
