Document Summary
Four different paints are advertised as having the same drying times. Five samples were randomly selected from each of the four paints and the drying times were recorded in minutes. Use the partial anova table below to answer questions 1 - 7: The f test statistic for testing differences in average drying times is. 1. 91 none of the above: at . 05 level of significance, the critical f value is. Suppose you wanted to use the tukey-kramer procedure to test the differences in the drying times for all possible pairs of paints, the critical range is. The average drying times for paints 1 and 2 are significantly different. The average drying times for paints 3 and 4 are significantly different. Suppose that the average drying times were 31. 6 minutes, 38. 2 minutes, 35. 3 minutes, and 28. 7 minutes for paints 1, 2, 3, and 4, respectively. Suppose also that the critical range had been 15. 0 minutes.
