Suppose that we will randomly select a sample of 69 measurements from a population having a mean equal to 22 and a standard deviation equal to 8. (a) describe the shape of the sampling distribution of the sample mean . do we need to make any assumptions about the shape of the population? why or why not? (b) find the mean and the standard deviation of the sampling distribution of the sample mean . (round your σx¯ answer to 1 decimal place.) (c) calculate the probability that we will obtain a sample mean greater than 24; that is, calculate p( > 24). hint: find the z value corresponding to 24 by using µ and σ because we wish to calculate a probability about . (use the rounded standard error to compute the rounded z-score used to find the probability. round your answer to 4 decimal places. round z-scores to 2 decimal (d) calculate the probability that we will obtain a sample mean less than 20.253; that is, calculate p( < 20.253) (use the rounded standard error to compute the rounded z-score used to find the probability. round your answer to 4 decimal places. round z-scores to 2 decimal places.) next visit question mapquestion 1 of 15 total1 of 15 prevmcgraw hill education.
