You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly different from 0.27. You use a significance level of α=0.001α=0.001.       H0:p=0.27H0:p=0.27       H1:p≠0.27H1:p≠0.27 You obtain a sample of size n=406n=406 in which there are 97 successes.
