An IQ test is designed so that the mean is 100 and the standard deviation is 23 for the population of normal adults. Find the sample size necessary to estimate the
mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 7 IQ points of the true mean. Assume that o = 23 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
(Round up to the nearest integer.)
