Identify the action(s) that most likely contributed to the reduction in the standard deviation of visit times at the doctor’s office. For questions with multiple possible answers, an incorrect response cancels a correct response. For full credit, ONLY the correct response(s) must be selected

This is similar to the problem you have worked in Problem Set: Lesson 2: Problem 2: Visit times at the Doctor’s Office In a doctor’ office, the average time to complete the visit (from time of check-in to the end of the consultation with the doctor) for a patient is normally distributed with mean 20 minutes. Because of some actions taken at the office, the standard deviation has now REDUCED by 1 minute. So, the standard deviation is now 2 minutes. The Tables and Graph below show the Normal Distribution for the above scenario – the distribution of time from the time of check-in to end of the consultation with the doctor. Normal Distribution: Values by Standard Deviation Increment Mean 20 Standard Deviation 2 Std Dev from Mean Value (Mean + z*SD) Cumulative Percentile % of Distribution in Band -3.0 14.00 0.1% 0.1% -2.5 15.00 0.6% 0.5% -2.0 16.00 2.3% 1.7% -1.5 17.00 6.7% 4.4% -1.0 18.00 15.9% 9.2% -0.5 19.00 30.9% 15.0% 0.0 20.00 50.0% 19.1% 0.5 21.00 69.1% 19.1% 1.0 22.00 84.1% 15.0% 1.5 23.00 93.3% 9.2% 2.0 24.00 97.7% 4.4% 2.5 25.00 99.4% 1.7% 3.0 26.00 99.9% 0.5% Percentile and band % assume a normal distribution. “% of Distribution in Band” is the share of the distribution between this row and the row above (first row = area below -3.0 SD). The chart below marks the mean/median and the +/-2.5 SD and +/-5 SD points.
