At American Widgets in 2020, across salespeoplethe average annual sales was $500,000, with a standard deviation of $100,000. Assume that a given salespersons sales are positively but imperfectly correlated from one year to the next; in the past, year-to-year correlations have been about .5. Also, suppose that average sales (and the standard deviation in sales) across salespeople are expected to be the same in 2021as they were in 2020. (That is, assume the 2021overall average will be $500,000 and the 2021standard deviation will be $100,000.)Now consider salesperson Patty OFurniture --she had a quite goodyear in 2020, with $700,000 in sales.

Please explain your answer, and describe the intuitive basisof such a prediction.

2.(4pts) Based on the information available, which of the following would be themost appropriate(i.e., normative) prediction for Pattys 2021sales?

(a)$300,000

(f) $550,000

(b)$350,000

(g)$600,000

(c)$400,000

(h)$650,000

(d)$450,000

(i)$700,000

Describe your logicand show your work. (Hint: If youre having difficulty here, you may want to consider the method sketched out in Ch 18 of Kahnemans book.)

3.(3pts) Suppose that the year-to-year correlation in sales was .3rather than .5. How would this change the most appropriate prediction for Pattys 2021sales; would the prediction increase, decrease, or stay the same(compared to the answer to question 2)? Calculate the most appropriate prediction for Pattys 2021sales assuming a year-to-year correlation of .3.Describe your logic and/or show your work.
