Extracted text: An 1Q test is designed so that the mean is 100 and the standard deviation is 15 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% confidence that the sample mear is within 4 1Q points of the true mean. Assume that a= 15 and determine the required sample size using technology Then determine id this is a reasonable sample size for a real world calculation The required sample size isRound up to the nearest intoger) Would it be reasonable to sample this mumber of students? O Yes. This number of 1Q test scores is a fairly small number O Yes. This number of IQ test scores is a tairty large number. O No This number of IQ test scores is a fairly small number O No. This number of 1Q test scores is a fairly large number
