The alkaline batteries of a toy car were designed to last 35 hours, on average. However  lots of customers complained that the batteries were lasting less than 35 hours. You  decided to randomly sample 50 of the batteries. The mean of the sample was 29.3 hours,  and the sample standard deviation 2.8 hours. Is there sufficient evidence to support the  claim that the mean battery life is less than 35? Perform a hypothesis test at the 1%  significance level using the p-value approach
