Suppose the jewelry of exams has a population that is normally distributed with standarddeviation of 5. You are walking down the street and sample 9 exams from this populationand obtain a mean jewelry of 28.95 and a standard deviation of 6.3802. Using an alphavalue of a = 0.01, is this observed mean significantly different than an expected jewelry of27?
