Sprint LTE @ 8 31%D_ 8:12 PM webwork.uoregon.edu (1 point) For each problem, select the best response (a) A 95% confidence interval for the mean of a population is computed from a random sample and found to be 10 4 . We may conclude A. that if we took many, many additional samples and from each computed a 95% confidence interval for , approximately 95% of these intervals would contain B. 95% of the population is between 6 and C. that there is a 95% probability that is between 6 and 14 D. that there is a 95% probability that the true mean is 10 and a 95% chance the true margin of error is 4 O E. All of the above (b) Suppose you collect a SRS of size n from a population and from the data collected you computed a 95% confidence interval for the mean of the population. Which of the followin would produce a new confidence interval with larger width (larger margin of error) based on these same data? A. Use a larger confidence level B. Nothing can guarantee absolutely that you will get a larger interval. One can only
