Random sampling from four treatments produced the following data: Use Table 4.

Random sampling from four treatments produced the following data: Use Table 4. Calculate the grand mean. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.) Calculate SSTR and MSTR. (Round intermediate values to 4 decimal places and final answers to 2 decimal places.) Calculate SSE and MSE. (Round intermediate values to 4 decimal places and final answers to 2 decimal places.) Calculate the value of the F test statistic. (Do not round intermediate calculations. Round your answer to 2 decimal places.)

Explanation / Answer

(a) (3*13+4*10+5*10.4+3*18.3)/15 = 12.39

--------------------------------------------------------------------------------------------------------

(b)

SSTR=149.73

MSTR=49.91

--------------------------------------------------------------------------------------------------------

(c)SSE=55.87

MSE=5.08

--------------------------------------------------------------------------------------------------------

(e)F test statistic = 9.83

ANOVA table Source SS    df MS F    p-value Treatment 149.73 3 49.911 9.83 .0019 Error 55.87 11 5.079 Total 205.60 14
