Assume that a sample is used to estimate a population mean μμ. Find the 80% confidence interval for a sample of size 457 with a mean of 66.5 and a standard deviation of 13.4. Enter your answer as a tri-linear inequality accurate to 3 decimal places. ____ < μ < ____
Assume that a sample is used to estimate a population mean . Find the 95% confidence interval for a sample of size 599 with a mean of 27.4 and a standard deviation of 6.9. Enter your answer as a tri-linear inequality accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
