When constructing a (1 - )% confidence interval for the population mean, the best interpretation of is: Question 8 options: the probability that the sample average is equal to the population mean the probability that the sample average does not lie within the confidence interval the probability that the population mean does not lie within the confidence interval Question 9 (1 point) Saved As alpha () increases, the probability that your confidence interval will contain the true population mean: Question 9 options: A) remains unchanged B) decreases C) increases Question 10 (1 point) Saved Suppose that alpha is equal to 5%. This means that you are: Question 10 options: A) only 5% confident that your confidence interval contains the true mean B) 95% confident that your confidence interval contains the true mean C) 90% confident that your confidence interval contains the true mean Question 11 (1 point) Saved When constructing a confidence interval you want the value of to be: Question 11 options: large small equal to 50% equal to 100% Question 12 (1 point) Saved You will get a more precise (tighter) confidence interval for the mean if the original data has a: Question 12 options: A) small standard deviation B) large standard deviation Question 13 (1 point) Saved As the sample size (N) increases, you will get a: Question 13 options: A) less precise (wider) confidence interval B) more precise (narrower) con
