Question:

Refer to the data on the girth, in centimeters, of grizzly bears in Table D.6 of the Data Bank. A computer calculation for a test of H0: Î¼ = 100 centimeters versus H1: Î¼ ‰ 100 gives
One-Sample Z: Girth
Test of mu = 100 vs mu not = 100

(a) What is the conclusion if you test with Î± = .027
(b) What mistake could you have made in part (a)?
(c) Before you collected the data, what was the probability of making the mistake in part (a)?
(d) Give a long-run relative frequency interpretation of the probability in part (c).
(e) Give the P-value of your test with a = .02.
