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 statistics students such that it
can be said with 90% confidence that the sample mean is within 7 IQ points of the true mean. Assume that o=13 and determine the required sample size using technology. Then determine if this is a reasonable
sample size for a real world calculation.
