An IQ test is designed so that the mean is 100 and the standard deviation is 18 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 at the sample mean s within 5 Q poln softhe true mea Assume that σ 18 and determine the required sample size using technology. Then determine if this is a reasonable sample size for...
An IQ test is designed so that the mean is 100 and the standard deviation is 22 for the population of normal adults. Find the sample size necessary to estimate the mean I score of statistics students such that it can be said with 90% confidence that the sample mean is within 40 points of the true mean.
