A student wants to estimate the mean score of all college students for a particular exam. First use the range rule of thumb to make a rough estimate of the standard deviation of those scores. Possible scores range from 800 to 1000. Use technology and the estimated standard deviation to determine the sample size corresponding to a 99% confidence level and a margin of error of 100 points. What isn't quite right with this exercise? The range rule of thumb estimate for the standard deviation is (Type an integer or a fraction.) A confidence level of 99% requires a mimimum sample size of (Round up to the nearest integer.) What isn't quite right with this exercise? O A. A minimum sample size of 2 is not feasible to use to estimate the mean test scores. O B. A margin of error of 100 points seems too high to provide a good estimate of the mean score. OC. These results don't apply to a test that has multiple choice questions. O D. The range rule of thumb introduces too much inaccuracy for this procedure.
