) Consider the following regression results based on 30observations.
y = 238.33 – 0.95x1 + 7.13x2 + 4.76x3; SSE = 3,439
y = 209.56 – 1.03x1 + 5.24(x2 + x3); SSE = 3,559
a. Formulate the hypotheses to determine whether the influencesof x2 and x3 differ in explaining y.
b. Calculate the value of the test statistic.
c. At the 5% significance level, find the critical value(s).
d. What is your conclusion to the test?
