A normally distributed population has a mean of 425 and a standard deviation of 80. a. Determine the probability that a random sample of size 16 selected from this population will have a sample mean less than 387. b. Determine the probability that a random sample of size 25 selected from the population will have a sample mean greater than or equal to 461, P(i<387) -D (Round to four decimal places as needed.) a
