Question

6. Consider the experiment in Exercise 3. Suppose some of the chickens were lost during the course of the experiment, resulting in the following set of observations.

Treatment	Serum T3, (ng/dl) x 10(-1)
Premolt	90.09	90.45	99.38	73.56
Fasting	98.81	103.55	115.23	129.06	117.61
60g bran	197.18	207.31	177.5
80 g bran	102.93	117.51	119.92	112.01	101.1
Laying mash	82.94	83.14	89.59	87.76

e.       How has the loss of some chickens from the experiment affected the estimates of the means?

f.        Compute the 95 % confidence interval estimates of the treatment means.

g.      Test the hypothesis of no differences among means of the five treatments with the F test at the .05 level of significance.

h.      Write the normal equations for the data.
