The melting point of each of 16 samples of a certain brand of hydrogenated vegetable oil was determined, resulting in top enclose average of 94.32. assume that the distribution of melting point is normal with standard deviation 1.2. suppose a researcher suspects that the real mean melting point is not equal to 95. set up the hypothesis test in symbolic format.
for the same setting as problem 1, if the true mean is 94, the desired type one error is 0.05, type two error is 0.01, what is the minimum sample size?
