- John Kittle, an independent insurance agent, uses a five-year moving average to forecast the number of claims made in a single year for one of the large insurance companies he sells for. He has just discovered that a clerk in his employ incorrectly entered the number of claims made four years ago as 1,400 when it should have been 1,200.a. What adjustment should Mr. Kittle make in next year’s forecast to take into account the corrected value of the number of claims four years ago?b. Suppose that Mr. Kittle used simple exponential smoothing with a = .2instead of moving averages to determine his forecast. What adjustment is now required in next year’s forecast? (Note that you do not need to know the value of the forecast for next year in order to solve this problem.)In the last three years, there have been changes of 55%, 3% and 2% in the production amount of a good, respectively.

Complete parts (a) through (c) below. Click the icon to view the side-by-side bar graph. (a) Does the graph suggest that grade inflation is a problem in colleges? A. Yes, because the GPAS increased over time for all schools. B. No, because nothing can be concluded about individual GPAS from the averages. C. No, because the GPAS are different for each time period. D. Yes, because the GPAS are greater for private schools for every time period. (b) In public schools, the average GPA was 2.86 in 1991-1992 and 3.02 in 2006-2007.
