A batch of cookies is sent out for sale if more than 95% pass a yum test. Rather than test every cookie in the batch, they only test sample n=250 from each batch. In batch #42, of the 250 cookie tests, 245 of them passed the yum test. Using this data, test the null hypothesis that H0: p=.95 vs Ha: p>.95 at the a=.1 level. What is the p-value of this test, and what is your conclusion?
