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 500 to 2000. 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? A. The range rule of thumb introduces too much inaccuracy for this procedure. B. Amargin 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. A student wants to estimate the mean score of all college students for a particular exam.

Question
Transcribed Image Text: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 500 to 2000. 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?
A. The range rule of thumb introduces too much inaccuracy for this procedure.
B. Amargin 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.
