A research report claims that mice with an average life span of 32 months will live to be about 39 months old when​ 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that μ<39 if 64 mice that are placed on this diet have an average life of 38 months with a standard deviation of 3.3 ​months? Use a​ P-value in your conclusion.

Question

A research report claims that mice with an average life span of 32 months will live to be about

39

months old when​ 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that

μ<39

if

64

mice that are placed on this diet have an average life of

38

months with a standard deviation of

3.3

​months? Use a​ P-value in your conclusion.

A research report claims that mice with an average life span of 32 months will live to be about 39 months old when 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that u< 39 if 64 mice that are placed on this diet have an average life of 38 months with a standard deviation of 3.3 months? Use a P-value in your conclusion. Click here to view page 1 of the table of critical values of the t-distribution. Click here to view page 2 of the table of critical values of the t-distribution. Identify the null and alternative hypotheses. VB. Ho: µ= 39 OC. Ho: u> 39 O A. Ho: µ= 39 Η: μ> 39 H1: µ< 39 H1: µ= 39 Ο D. H μ= 39 ΟΕ Ho μ#39 OF. Ho: H< 39 H,: µ# 39 H1: µ= 39 H1: µ= 39 Find the test statistic. (Round to two decimal places as needed.)
