Assume that the sample is a simple random sample obtained from a normally distributed population of IQ scores of statistics professors. Use the table below to find the minimum sample size needed to be 95% confident that the sample standard deviation s is within 50% of sigma. a. The minimum sample size needed is ### Sample Size Requirements for Estimating the Population Standard DeviationThis table outlines the minimum sample sizes needed to be confident that the sample standard deviation (s) falls within a certain percentage of the population standard deviation (σ). The confidence levels considered are 95% and 99%.#### 95% Confidence Level:- **1%** of σ: Sample size should be at least **19,205**- **5%** of σ: Sample size should be at least **768**- **10%** of σ: Sample size should be at least **192**- **20%** of σ: Sample size should be at least **48**- **30%** of σ: Sample size should be at least **21**- **40%** of σ: Sample size should be at least **12**- **50%** of σ: Sample size should be at least **8**#### 99% Confidence Level:- **1%** of σ: Sample size should be at least **33,218**- **5%** of σ: Sample size should be at least **1,336**- **10%** of σ: Sample size should be at least **336**- **20%** of σ: Sample size should be at least **85**- **30%** of σ: Sample size should be at least **38**- **40%** of σ: Sample size should be at least **22**- **50%** of σ: Sample size should be at least **14**

An IQ test is designed so that the mean is 100 and the standard deviation is 17 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 90% confidence that the sample mean is within 4 IQ points of the true mean. Assume that sigma equals 17 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. a. The required sample size is (Round up to the nearest integer.)
