claims that mice ige life span of 32 months will live to be about 40 months old when 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that <40 if 70 mice that are placed on this diet have an average life of 38 months with a standard deviation of 6.8 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 40 months old when 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that μ<40 if 70 mice that are placed on this diet have an
average life of 38 months with a standard deviation of 6.8 months? Use a P-value in your conclusion.

sufficient evidence that mice with an average life span of 32 months will live to be
than 40 months old when 40% of the calories in their diet are replaced by vitamins and protein.
Transcribed Image Text:A research report claims that mice with an average life span of 32 months will live to be about 40 months old when 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that μ<40 if 70 mice that are placed on this diet have an average life of 38 months with a standard deviation of 6.8 months? Use a P-value in your conclusion.
