Question: The presence of harmful insects in farm fields is detected by erecting boards covered with a sticky material and then examining the insects trapped on the board. To investigate which colors are most attractive to cereal leaf beetles, researchers placed six boards of each of four colors in a field of oats in July. The table below gives data on the number of cereal leaf beetles trapped:

Lemon yellow White Green Blue

At the .05 significance level, can we conclude there is a difference in the mean of the four colors? ANOVA
