Find the sample size necessary to estimate themean IQ score of statistics students such that it can be said with 95% confidence that the sample mean is within 2 IQ points of the true mean. Assume that o 12and 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(Round up to the nearest integer.)Would it be reasonable to sample this number of students?O Yes.
