If we were to redo a study twenty times and calculate twenty 90% confidence intervals for the mean, 2 or so of our confidence intervals would not contain the true mean. TRUE OR FALSE
Added by Kristi A.
Step 1
If we were to redo the study twenty times and calculate twenty 90% confidence intervals, we would expect that 90% of these intervals would contain the true mean. Since 90% of 20 is 18, we would expect that 18 out of the 20 confidence intervals would contain the Show more…

Assume that we are constructing a confidence interval for the difference in the means of two populations based on independent random samples. If both sample sizes n1 and n2 =10, and the distributions of both populations are highly skewed, then a confidence interval for the difference in the means can be constructed using the t test statistic. TRUE OR FALSE

Suppose that you obtained data by taking a random sample from a population and that you intend to find a confidence interval for the population mean. Answer True or False to the following question: Increasing the confidence level from 95% to 99% will decrease the margin of error.
