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.

Identify the null and alternative hypotheses. Ο Α Η: μ# 38 H1: µ= 38 B. Ho: μ= 38 H4:µ< 38 Ho: µ> 38 H1: µ= 38 Ο D. H0: μ= 38 H1: µ#38 E. H: μ= 38 H4:µ> 38 ΟF H: μ< 38 H1:µ= 38 Find the test statistic. (Round to two decimal places as needed.)

Consumer agencies claim that the mean lifespan of a dishwasher is 9.5 years. Your company manufacturers dishwasher and you have been asked to see if this claim is true. You randomly survey 20 households who have recently purchased a dishwasher and ask them how long their previous dishwashers lasted and you calculate a mean of 8.9 years with a standard deviation of 3.1.
