Question: The sample mean is $58.52 The sample standard deviation is $2.54 Determine if the average retail price has fallen from $59.26 by calculating the probability

The sample mean is

$58.52

The sample standard deviation is

$2.54

Determine if the average retail price has fallen from

$59.26

by calculating the probability that a random sample of size 200 would result in a sample mean no larger than the sample mean calculated in part a. Assume that the population mean is

$59.26

and that the sample standard deviation is representative of the population standard deviation.The probability of obtaining a sample with a mean no larger than the sample mean calculated previously is
