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 2 IQ points of the true mean. Assume that Ơ = 25 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. (a) The required sample size is ____. (Round up to one integer as needed) (b) Is this sample size reasonable?
