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

Expert Solution

(5) Conclusion

at the 0.05 significance level there is enough evidence to claim that there is no difference between the mean daily driving time for the population of 16-20 year old men and the mean daily driving time for the population of men 60 years and older
