You need to compute a 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 .8? (Use 5.5 as an estimate of the population standard deviation from prior studies.)UseTable 1.(Round intermediate calculations to 4 decimal places. Round "z-value" to 3 decimal places. Round up your answer to the nearest whole number.)
