Consider a population with a mean u = 198 and standard deviation o = 66. Suppose random samples of size n = 76 are selected from this population. 1. a) What is the mean of the distribution of the sample mean? b) What is the standard error of the mean? (2 decimal places) On = In the following questions, round the standard error and z-scores to exactly 2 decimal places before determining probabilities. Report probabilities accurate to at least 3 decimal places. 2. What is the probability that a randomly selected sample mean is: a) less than 201? b) greater than 193.2? c) less than 201 and greater than 193.2? d) less than 201 given greater than 193.2? e) less than 201 or less than 193.2
