An IQ test is designed so that the mean is 100 and the standard deviation is 13 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of nurses such that it can be said with 95% confidence that the sample mean is within 5 IQ points of the true mean. Assume that sigmaσequals=13 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is nothing. (Round up to the nearest integer.) would it be reasonable to sample this number of nurses?

Question
An IQ test is designed so that the mean is 100 and the standard deviation is 13 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of nurses such that it can be said with 95% confidence that the sample mean is within 5 IQ points of the true mean. Assume that
sigmaσequals=13
and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation.The required sample size is
nothing.
(Round up to the nearest integer.)would it be reasonable to sample this number of nurses?
