A researcher is interested in estimating the mean cholesterol level in men. Based on a simple random sample of 54 men, the 95% confidence interval for the population mean μ was 189.9 < μ < 210.1
A. If 100 different samples of size 54 are selected, and based on each sample, a confidence interval was constructed, exactly 95 of these confidence intervals would contain the true value of μ.
B. If many different samples of size 54 are selected and, based on each sample, a confidence interval was constructed, in the long run, 95% of the confidence intervals would contain the true value of μ.
C. There is a 95% chance that the true value of μ lies between 189.9 and 210.1.
D. If many different samples of size 54 are selected and, based on each sample, a confidence interval was constructed, 95% of the time the true value of μ would lie between 189.9 and 210.1.
Homework Answers

Let's say we have constructed a 95% confidence interval estimate for a population mean. Which of the following statements would be correct? A. We expect that 95% of the intervals so constructed would contain the true population mean. B. We are 95% sure that the true population mean lies either within the constructed interval or outside the constructed interval. C. Taking 100 samples of the same size, and constructing a new confidence interval from each sample, would yield five intervals...

The mean total cholesterol level for men being treated for obesity is 175 with a standard deviation of 25. Samples of size 150 are drawn from the population. What is the mean of the sample means? What is the standard error of the sample means? Construct a 95% confidence interval around the mean and interpret it. Use the context of the question please.

Assignment 2: Connection between Confidence Intervals and Sampling Distributions: The purpose of this activity is to help give you a better understanding of the underlying reasoning behind the interpretation of confidence intervals. In particular, you will gain a deeper understanding of why we say that we are “95% confidentthat the population mean is covered by the interval.” When the simulation loads you will see a normal-shaped distribution, which represents the sampling distribution of the mean (x-bar) for random samples of...

A researcher is interested in finding a 90% confidence interval for the mean number of times per day that college students text. The study included 112 students who averaged 26.7 texts per day. The standard deviation was 24.9 texts. If many groups of 112 randomly selected members are studied, then a different confidence interval would be produced from each group. About _____ percent of these confidence intervals will contain the true population number of texts per day and about _____...
