An IQ test is designed so that the mean is 100 and the standard deviation is 8 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 99% condence that the sample mean is within 2 IO points of the true mean. Assume that a = 8 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. E> The required sample size is D. (Round up to the nearest integer.) Would it be reasonable to sample this number of students? 0 Yes. This number of IQ test scores is a fairly small number. 0 Yes. This number of IQ test scores is a fairly large number. 0 No. This number of IQ test scores is a fairly large number. 0 No. This number of IQ test scores is a fairly small number.
