We want to obtain a sample to estimate a population mean. Based on previous evidence, researchers believe the population standard deviation is approximately 52.4. We would like to be 95% confident that the estimate is within 4 of the true population mean. How large of a sample size is required?

A group of statistics students decided to conduct a survey at their university to find the average (mean) amount of time students spent studying per week. Assuming a population standard deviation of thirteen hours, what is the required sample size if the error should be less than a half hour with a 95% level of confidence?

You want to estimate the proportion of students at your college or university who are employed for 10 or more hours per week while classes are in session. You plan to present your results by a 95% confidence interval. Using the guessed value p* = 0.25, find the sample size required if the interval is to have an approximate margin of error of m = 0.06.
