Question: The null and alternative hypothesis for a test are Ho: U=0.6 and Ha: U>0.6, respectivy, where U is the mean cadmium level in a species

The null and alternative hypothesis for a test are Ho: U=0.6 and Ha: U>0.6, respectivy, 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 = .39 (ii) alpha = .05 (iii) n = 12 (iv) U = 0.65 , 0.70 , 0.75 , 0.80

Please determine the probability of a type I error for the following .65 , .70 , .75 , .80
