A Stat 510 student works at the IT Help Desk at Hale Library. For several weeks, the student recorded how long it took to solve the walk-in problems she attended. A random sample of n= 14 walk-in problems was selected and times are listed below. 18.60 19.30 18.48 12.88 17.02 14.62 17.36 17.50 22.18 22.17 17.51 18.92 19.52 20.31
9. A classmate offers the following interpretation of the C.I. you obtained in the previous question: "The probability that the mean time it takes for the student to solve a walk-in problem is within the calculated C.I. is 0.90". Is this interpretation correct? (a) Yes, it is. (b) No, it is not. (c) Maybe, it depends on the symmetry of the data. (d) Maybe, it depends on the sample size.
