The average height of students in a freshman class of a certain school has been 165.24 cm with a population standard deviation of 5.56 cm. Is there a reason to believe that there has been a change in the average height if a random sample of 37 students in the present freshman class has an average height of 169.42 cm? Use a 0.01 level of significance. a. "No, there is no sufficient evidence to say that the height of the freshmen students changed based on empirical evidence because the calculated z is in the critical region." b. "Yes, there is sufficient evidence to believe that the height of the freshmen students changed based on empirical evidence because the calculated z is in the critical region." c. "Yes, there is sufficient evidence to believe that the height of the freshmen students changed based on empirical evidence because the calculated z is not in the critical region." d. "No, there is no sufficient evidence to say that the height of the freshmen students changed based on empirical evidence because the calculated z is not in the critical region."
