An IQ test is designed so that the mean is 100 and the standard deviation is 1717 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 9595% confidence that the sample mean is within 88 IQ points of the true mean. Assume that sigmaσequals=1717 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is 1717. (Round up to the nearest integer.) Would it be reasonable to sample this number of students? YesYes. This number of IQ test scores is a fairly smallsmall number. YesYes. This number of IQ test scores is a fairly largelarge number. NoNo. This number of IQ test scores is a fairly smallsmall number. NoNo. This number of IQ test scores is a fairly largelarge number.
