If µ equals 42, what percentage of all possible sample means are greater than or equal to 42.95? Since we have actually observed a sample mean of Picture = 42.95, is it more reasonable to believe that (1) µ equals 42 and we have observed a sample mean that is greater than or equal to 42.95 when µ equals 42, or (2) that we have observed a sample mean that is greater than or equal to 42.95 because µ is greater than 42?
