Use conest function in R to test the following contrasts. Knowing that these contrasts were developed a priori, interpret the results. Include all relevant output. Apply the appropriate experiment wise error rate control. Describe the null hypotheses to be tested by these contrasts. Did you reject or accept these hypotheses, and why? What do these results indicate with respect to the context of the problem at hand (e.g. relate this to pituitary function, chemicals, and control).
