.Suppose that you are a researcher interested in determining how often wild pigs will fight on the basis of what type of animal it is exposed to. You obtain a sample of 28 pigs.You show each pig a picture (Picture Type) of a Wolf, or a Bear, or a Panther, or another Boar.You record how many times it tries to attack the picture in an hour's time.You also think that the attacking behavior might be related to tusk size, so, you include tusk size (in inches) as a covariate.You obtain the following data for your four groups of seven boars each.

Perform the appropriate statistical test on the above data--- be sure to include the null hypothesis and the decision reached.Also, provide the table of adjusted/estimated means for the Picture Type Factor.What does this table mean?
