Consider the television picture tube brightness experiment
Chapter 9, Problem 168SE(choose chapter or problem)
Consider the television picture tube brightness experiment described in Exercise 8-37.
(a) For the sample size \(n=10\), do the data support the claim that the standard deviation of current is less than 20 microamps?
(b) Suppose that instead of \(n=10\), the sample size was 51 . Repeat the analysis performed in part (a) using \(n=51\).
(c) Compare your answers and comment on how sample size affects your conclusions drawn in parts (a) and (b).
