A new procedure mixing Calcium hydroxide and Calcium silicate hydride nanotubes with concrete has been developed, and the strengths of various concrete specimens have been measured based on the relative proportion of calcium hydroxide and calcium silicate hydride tubes.3 treatments are shown in the table below, 100% calcium hydroxide, 50% Calcium Hydroxide and 50% Calcium silicate hydride, and 100% calcium silicate hydride, all added as ~ 1% of the mixture to the concrete . Eight samples of each were used to produce the means and variances. A) Run ANOVA on this data to see if there are any differences B) Why might classical ANOVA be inappropriate for this data set?

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.)
