Question: The standard deviation for this population is probably less than 15 because it is a group with less variation than a group randomly selected from

The standard deviation for this population is probably less than 15 because it is a group with less variation than a group randomly selected from the general population; therefore, if we use s = 15 we are being conservative by using a value that will make the sample size at least as large as necessary. Assume then that s = 15 and determine the required sample size. Does the sample size appear to be reasonable?
