O A. As the sample size decreases, the margin of error decreases ○ B. AS the sample size nonases, the margin of error stays the same. O C. As the sample size inoreases, the margin of error decreases ○ C. As te percent confdence deoreases, the size of the interval increases
How does increasing the sample size affect the margin of error, E? O A. O B. As the sample size increases, the margin of error stays the same. As the sample size decreases, the margin of error decreases. OC. As the sample size increases, the margin of error decreases. (c) Compute the 99% confidence interval about if the sample size, n, is 30. A 99% confidence interval is (1 1,1 1) (Use ascending order. Round to two decimal places as needed.) Compare the 99% confidence interval to the 90% confidence interval obtained in part (a). O A. As the percent confidence increases, the size of the interval increases. O B. As the percent confidence increases, the size of the interval stays the same. ° C. As the percent confidence decreases, the size of the interval increases. How does increasing the level of confidence affect the size of the margin of error, E? O A. As the percent confidence increases, the margin of error increases. O B. As the percent confidence decreases, the margin of error increases. O C. As the percent confidence increases, the margin of error stays the same. (d) Can we compute a confidence interval about u based on the information given if the sample size is n 15? A. Yes, but only if the population is normal. O B. No, an interval can only be based on a population if n 2 30. O C. Yes, there are no conditions on the population. Click to select your answer(s). Save for L ator
