The recent cadets of ’21 in the military academy you a re employed in boast thatthey have much better training time records compared to cohorts of previous years. In a training that requires rigorous physical endurance and dexterity, the soldiers attempt to finish the course as soon as they canand their performance is measured in minutes.

A rchives show that the rest of the cadets combined had a mean of 20 minutes and standard deviation of 10 minutes.

A.Identify the appropriate statistical procedure to apply.
