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=???

You need to compute the an 90% 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 2.6? (Use 12.4 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.) What is the sample size?

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 2.1? (Use 8.4 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:

We have provided a sample mean, sample size, sample standard deviation, and confidence level. In each case, use the one-mean t-interval procedure to find a confidence interval for the mean of the population from which the sample was drawn. $$\bar{x}=50, n=16, s=5, \text { confidence level }=99 \%$$
