The mean drying time of a certain paint in a certain application is 12 minutes. A new additive will be tested to see if it reduces the drying time. Sixty-four specimens will be painted, and the sample mean drying time will be computed. Assume the population standard deviation of drying times is 1.6 minutes. Let u be the mean drying time for the new paint. Assume that unknown to the investigator, the true mean drying time of the new paint is 11.4 minutes. a) What are the null and alternative hypotheses for this hypothesis test
