A recipe submitted to a magazine by one of its subscribers states that the mean baking time for a cheesecake is 57 minutes. A test kitchen preparing the recipe before it is published in the magazine makes the cheesecake 12 times at different times of the day in different ovens. The following baking times (in minutes) are observed. 52 54 55 57 60 63 64 64 66 64 65 66 Assume that the baking times belong to a normal population. (a) Test the null hypothesis that the mean baking time is 57 minutes against the alternative hypothesis 57. Use a=.05. (b) What is the P value?
