Question

2.) According to the central limit theorem the sampling distribution for a sample mean X? should be normally distributed. Given the random variable X represents the quiz score for a given student in a given class and has population mean ?? = 75 and standard deviation ?? = 15. a.) What is the mean and standard deviation for the sampling distribution of X? if it is the average of n = [16] quizzes? ??? = ??? = b.) What is the probability that a random student will receive a C or better average? P(70 ? X?) =
