An IQ test is designed so that The mean Is 100 and the standard deviation is eight 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 with 99% confidence that the sample mean is within two IQ points of the true mean. Assume that o=8 And determine the required sample size using technology. Then determine if this is a reasonable sample size for the real world calculation. What is the required sample size
