The p-value for the f test for interaction

Reference no: EM138093

1. An experiment was conducted to determine the effects of three different pesticides (P1,P2,P3) on the yield of three different varieties of citrus tree (V1,V2,V3). Two trees of each variety were randomly selected from the orchard, and the three pesticides were than randomly assigned to the trees; two trees for each pesticide. Yields of fruit, in bushels per tree, were obtained after the test period. A partial ANOVA table is given below.

The P-value for the F test for main effect for pesticide is

A. less than 0.001.
B. between 0.025 and 0.050.
C. greater than 0.10.

2. An experiment was carried out to assess the effects of four tomato varieties and four planting densities on yield. There were 64 plots, and each of the 16 factor combinations was randomly assigned to 4 plots. A partial ANOVA table is given below.
