An iq test is designed so that the mean is 100 and 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 95% confidence that the sample mean is with 4 iq points of the true mean. assume that standard deviation =13 and determine the required sample size using technology. then determine if this is a reasonable sample size for a real world calculation.
