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. A random sample of 45 home theater systems has a mean price of $114.00. Assume the population standard deviation is $15.30. Construct a 90% confidence interval for the population mean.

Below you will find questions and a sample dataset. Please use the provided dataset to complete the tasks and to answer the questions. Assuming that the following sample is taken from a normal distribution, compute the 90% confidence interval for the population mean. Dataset: 31.6 46.9 54.5 23.7 60.3 37.6 58.3 65.7 50.2 53.7 A telecommunication company wants to estimate the mean length of time (in minutes) that 18- to 24- year-olds spend text messaging each day. In a random sample of fifty-eight 18- to 24-year-olds, the mean length of time spent text messaging was 29 minutes. From past studies, the company assumes that σ is 4.5 minutes and that the population of times is normally distributed. Compute a 99% confidence interval for the population mean time that 18- to 24-year-olds spend text messaging each day. Interpret the confidence interval found in part a. What does the phrase “99% confidence” refer to in this context?…
