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.
