s. As you increase the margin error of a confidence interval, the confidence level (Note: Assume the sample size is fixed.) A) increases B) decreases C) remains the same when constructing confidence intervals, the center of each interval is always- A) B) 9, the median the margin of error D) the mode 10. The basic form of a confidence interval is A) B) C) D) estimate± margin of error margin of error estimate standard emor± estimate estimate ±margin 11. True or False. Confidence intervals are resistant to outliers in the data set A) True B) False 12. The margin of error in a confidence interval is necessary to account for A) random sampling errors B) undercoverage C) nonresponse D) design errors 3. What is needed to compute a margin of error A) Sample size, standard deviation, and : B) Sample mean, sample size, and: C) Sample median, sample mean, and sample size D) Sample median, sample size, standard deviation, and: Please solve these problems and why we choose the answers. Thanks!Explanation / Answer
Solution:-
8) (A) By increasing the margin of error of a confidence interval, the confidence level increases.
9) (C) When constructing the confidence interval s, the center of each interval is always xbar.
10) (A) The basic form of confidence interval is estimate + Margin of error.
11) (B) False
