Jeremiah wants to estimate the mean age of students at his large university. He'll sample n students and make a 95%, percent con
fidence interval for the mean age. He is willing to use σ=3 years as an estimate of the standard deviation, and he wants the margin of error to be no more than 1 year. Which of these is the smallest approximate sample size required to obtain the desired margin of error?
D is the answer because, collision insurance will reimburse the insured for any damage sustained to their personal automobile that is due to the fault of the insured driver. Hope this helps.
