The estimate of the population proportion is to be within plus or minus 0.04, with a 98% level of confidence. The best estimate of the population proportion is 0.16. How large a sample is required? (Use z Distribution Table.) (Round the z-values to 2 decimal places. Round up your answer to the next whole number.)

You need to compute the a 95% confidence interval for the population mean. How large a sample should you draw to ensure that the sample mean does not deviate from the population mean by more than 1.0? (Use 5.0 as an estimate of the population standard deviation from prior studies.) (You may find it useful to reference the z table. Round intermediate calculations to at least 4 decimal places. Round "z" value to 3 decimal places. Round up your answer to the nearest whole number.) Sample Size=???
