A simple random sample of size n is drawn The sample mean x is found to be 18 1 and the sample standard deviation s is found to be 4 2 Click the icon to view the table of areas under the t distribution OC The margin of error increases c Construct a 99 confidence interval about u if the sample size n is 35 Lower bound 16 16 Upper bound 20 04 Use ascending order Round to two decimal places as needed Compare the results to those obtained in part a How does increasing the level of confidence affect the size of the margin of error E OA The margin of error does not change OB The margin of error decreases C The margin of error increases d If the sample size is 13 what conditions must be satisfied to compute the confidence interval OA The sample must come from a population that is normally distributed and the sample size must be large B The sample data must come from a population that is normally distributed with no outliers C The sample size must be large and the sample should not have any outliers
