The null and alternative hypothesis for a test are Ho: U = .08 and Ha: U > .8, respectively, where U is the mean cadmium level in a species of mushroom in parts per million (ppm). Given below are (i) the population standard deviation, sigma, (ii) a significance level, (iii) a sample size, and (iv) some values of U.

(i) sigma = .38 (ii) alpha = .10 (iii) n = 20 (iv) U = .82 , .84, .86, .88

Determine the probability of a type II error for the following .82 , .84 , .86 , .88
