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 100 to 1200. Use technology and the estimated standard deviation to determine the sample size corresponding to a 90% 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 90% requires a mimimum sample size of (Round up to the nearest integer.) What isn't quite right with this exercise? O A. The range rule of thumb introduces too much inaccuracy for this procedure. B. A margin of error of 100 points seems too high to provide a good estimate of the mean score. c. 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 100 to 1200. Use technology and the estimated
standard deviation to determine the sample size corresponding to a 90% 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 90% requires a mimimum sample size of
(Round up to the nearest integer.)
What isn't quite right with this exercise?
O A. The range rule of thumb introduces too much inaccuracy for this procedure.
B. A margin of error of 100 points seems too high to provide a good estimate of the mean score.
c. These results don't apply to a test that has multiple choice questions.
