Claim: there is no difference between the mean daily driving time for the popuation of 16-20 year old men and the mean daily driving time for the population of men 60 years and older. In a study of times that people drive each day, it was found that 50 men aged 16-20 years drove a daily average of 49.3 minutes with a standard deviation of 21.4 minutes, and 55 men aged 60 years and older drove a daily average of 57.1 minutes with a standard deviation of 35.6 minutes.Test the claim at the 0.05 significance level
