A machine that produces ball bearings is set so that the average diameter is 0.47 inch. A sample of 10 ball bearings was measured with the results shown below.
Assuming that the standard deviation is 0.06 inch, can we conclude at the 8% significance level that the mean diameter is not 0.47 inch?
A. The value of the standardized test statistic:
Note: For the next part, your answer should use interval notation. An answer of the form is expressed (-infty, a), an answer of the form is expressed (b, infty), and an answer of the form is expressed (-infty, a)U(b, infty).
B. The rejection region for the standardized test statistic:
C. The p-value is
D. Your decision for the hypothesis test: A. Reject . B. Reject . C. Do Not Reject . D. Do Not Reject .
In order to get credit for this problem all answers must be correct.
