An instructor is trying to determine the amount of time needed to complete a particular assignment. She takes a sample of 16 students and asks each one to keep track of their time with the following results in hours: (You may assume that the population of all times is normal.) 126.96.36.199.188.8.131.52.8 0.60.20.81.184.108.40.206.0 a.(3) Construct a 95% confidence interval for the amount of time needed for the assignment. _________________________ b.(2) What is the point estimate for the mean of the population? _______________________ c.(2) What is the margin of error of the estimate? __________________________ d.(3) Interpret the interval in the context of the problem Solution n=16 S=0.463 X=1.0125 t(0.025,15)=2.13144955 95%CI is (1.0125-0.246<<1.0125+0.246)=(0.7665,1.2585).
