1. Suppose you are calculating an Analysis of Variance for a completely randomized design. You are testing the hypotheses:
H0: µ1 = µ2 = µ3 = µ
H1: at least one µ1 not equal to µ
Suppose the resulting p-value = .001. How would you plot the raw data for this situation (you are expected to provide a sketch of the correct format of such a plot) and what would you expect the plot to show?
2. The probability density function for Y, a random variable, is given by
f(y) = 0.5 0
0 otherwise
2.1 What is the mean value of Y?
2.2 What is the variance of Y?
