A research report claims that mice with an average life span of 32 months will live to be about 38 months old when 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that u < 38 if 69 mice that are placed on this diet have an average life of 36 months with a standard deviation of 14.2 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 38
months old when 40% of the calories in their diet are replaced by vitamins and protein. Is there
any reason to believe that µ< 38 if 69 mice that are placed on this diet have an average life of
36 months with a standard deviation of 14.2 months? Use a P-value in your conclusion.

Identify the null and alternative hypotheses.
A. Ho: µ+ 38
H4:µ= 38
В. Но: 3 38
H1:µ< 38
Ho:H> 38
H:µ= 38
Ο D. H0 : μ= 38
