The scores of individual students on a national test have a normal distribution with mean 18.6 and standard deviation 5.2. At R. Torres National High School, 65 students took the test. If the scones at this school have the same distribution as the national scores, what are the mean and standard deviation of the sample mean for 65 students? (5 pts: 2 points mean. 3 points SD) Mean: SD: A random sample of n = 50 measurements is obtained from a population with p= i910 and or = 40. Compute for the mean and standard deviation of the sampling distribution for the sample means. (5 pts) Mean: SD
