Let X be the number of claims received (per week) by an insurance company. Based on 41 weeks of samples, x=18.5 and s=20.0. What is the 95% CI for ?

t-score 95% confidence interval and (df =40) = 2.021075...

95% CI for = [ x - ( 2.021075 * s / sqrt(41) , x + ( 2.021075 * s / sqrt(41) ]...........
= [ 12.18722 , 24.81278 ]............
