A researcher obtained a random sample of n=16 from a population with mu =70 and sigma =12. What is the probability that the sample mean will be (10 marks) a. p(M > 64) b. p(M < 79) c. between which two values should the sample mean fall with a probability of 0.95?
1) p(M > 64)
2) p(M < 79)
3) between 64 and 79
4) between 64 and 79 with a probability of 0.95
