Chapter 11.2, Problem 21BB

Equivalent Tests A X2 test involving a 2 × 2 table is equivalent to the test for the difference between two proportions, as described in Section 9-1. Using the claim and table in Exercise 9 “Four Quarters the Same as $1?” verify that the X2 test statistic and the z test statistic (found from the test of equality of two proportions) are related as follows: z2 = X2. Also show that the critical values have that same relationship.

A quality characteristic of a product is normally distributed with mean μ and standard deviation σ = 1. Speci- fications on the characteristic are 6≤x≤8. A unit that falls within specifications on this quality characteristic results in a profit of Co. However, if x 8, the profit is -C2. Find the value ofμ that maximizes the expected profit.
