OPER Health Center is rightfully worried about the need for additional physicians to cope with the increased patient flow. To see what the implications of increased flows would be, let us first investigate whether physicians are assigned efficiently in the current setting. Consider a typical day. The average numbers of patient arrivals to the health center during different times are shown in the following table. Time Slot Average Number of Patients # of physicans per hour 9-11am 32 9 11-1 pm 1-3 pm 20 23 10 9 3-5 pm 15 8 Coefficient of variation for the patient interarrival times is 1.4 and coefficient of variation for the activity times is 2. a) Compute the average waiting time to see a doctor for each time slot. (Remember that only 80% of patients visit the physicians). b) Suppose that the objective of BCG is to ensure that the average waiting time of a patient to see a physician is less than 25 minutes throughout the day (i.e., in each time slot) Develop a…2. A scatterplot shows a strong, positive, linear relationship between the number of rebounds a basketball team averages and the number of wins that team records in a season. Which conclusion is most appropriate? (A) A team that increases its number of rebounds causes its chances of winning more games to increase. (B) If the residual plot shows no pattern, then it is safe to conclude that getting more rebounds causes more wins, on average. (C) If the residual plot shows no pattern, then it is safe to conclude that getting more wins causes more rebounds, on average. (D) If the r^2r2 value is close enough to 100%, then it is safe to conclude that getting more rebounds causes more wins, on average. (E) Rebounds and wins are positively correlated, but we cannot conclude that getting more rebounds causes more wins, on average.
