A Hypothesis Testing Situation Is Given μ.\mu. To Draw the Power Curve

Question 42

Essay

A hypothesis testing situation is given. The population standard deviation, sample size, and significance level are given.Complete the table to give the probability of a Type II error and the power for each of the given values of µ. Use the table μ.\mu. to draw the power curve.
-A health insurer has determined that the "reasonable and customary" fee for a certain medical procedure is $1200. They suspect that the average fee charged by one particular clinic for this procedure is higher than $1200. The insurer wants to perform a hypothesis test to determine whether their suspicion is correct. Preliminary data analyses indicate that it is reasonable to apply a z-test. The hypotheses are H0:μ=$1200Ha:μ>$1200.\begin{array} { l } \mathrm { H } _ { 0 } : \mu = \$ 1200 \\ \mathrm { H } _ { \mathrm { a } } : \mu > \$ 1200 . \end{array} Assume that σ=$180,n=38\sigma = \$ 180 , \mathrm { n } = 38 , and the significance level is 0.100.10 . Find the probability of a Type II error and the power for μ=1190,1200,1210,1220,1230,1240,1250,1260,1270\mu = 1190,1200,1210,1220,1230,1240,1250,1260,1270 , 12801280 , 1290.1290 .
