You want to obtain a sample to estimate a population mean age of the incoming fall term transfer students. Based on previous evidence, you believe the population standard deviation is approximately o = 7.5. You would like to be 99% confident that your estimate is within 2.3 of the true population mean. How large of a sample size is required? n = Do not round between steps. Use technology to find z-score. Give your answer in whole people. Make sure you use the correct rounding rule for samples size.
