Solve the problems by following the steps and procedures in hypothesis testing. 1. An automobile manufacturer states that the mean kilometers per liter (kpl) for one of its new full-sized models is 15. Sixty cars of this model were randomly selected and the number of kilometers per liter consumed was recorded for each. The sample mean is 14.5 kpl with a standard deviation of 1.5 Do the data present sufficient evidence to indicate that the mean kpl for this model is less than 15? Use α = 0.05
