You intend to estimate a population mean u with the following sample. 65.1 91.2 84.5 65.9 80.5 105 You believe the population is normally distributed. Find the 90% confidence interval. Enter your answer as an open-interval (i.e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place). 90% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If convenient, use technology to construct the confidence intervals. 10. A random sample of 40 home theater systems has a mean price of $126.00. Assume the population standard deviation is $16.70. Construct a 90% confidence interval for the population mean. The 90% confidence interval is (nothing,nothing)
