Four different types of solar energy collectors were tested. Each was tested at four randomly chosen times, and the power (in watts) was measured, The results are listed in the table below. We have sampled to conclude whether there is a difference in the average energy output from each the four solar energy collectors. Collector A Collector B Collector C Collector D 1.9 1.6 1.2 1.4 1.6 1.5 0.9 1.0 2.0 1.6 1.2 1.4 1.8 1.9 0.9 1.3 We could test the averages from the solar collectors against each other in unique pairs. How many separate tests would that demand? (A) 4 (В) 16 (C) 6 . (D) 8 What hypotheses testing method should be used? (A) ANOVA (B) Matched Pairs Test (C) McNemar's Test (D) Shapiro-Wilk Test In order to use the test specified in problem 18, what three (3) conditions must be satisfied with samples above? From the sample data, there does seem to be significant evidence that there is a difference in the average energy output from each the four solar energy collectors. Why? (Be specific)
