To compare the effectiveness of three different types of phosphorescent coatings of airplane instrument dials, eight dials each are coated with the three types. Then the dials are illuminated by an ultraviolet light, and the following are the number of minutes each glowed after the light source was shut off: Type 1 Type 2 Type 3 52.9 58.4 71.3 62.1 55 66.6 57.4 59.8 63.4 50 62.5 64.7 59.3 64.7 75.8 61.2 59.9 65.6 60.8 54.7 72.9 53.1 58.4 67.3 a)- Is there a difference in the effectiveness of the three coatings? Use a =0.01. Null hypothesis HO: Alternative hypothesis H1: Statistic F = p-value = Decison: Is there a difference in the effectiveness of the three coatings? (yes or no)
