1.  An experiment to compare I = 5 brands of golf balls involved using a robotic driver to hit J = 7 balls of each brand. The resulting between-sample and within-sample estimates of s2 were MSTr = 123.50 and MSE = 22.16, respectively.
a.  State and test the relevant hypotheses using a signi cance level of .05.
b.  What can be said about the P-value of the test?
2.  The lumen output was determined for each of I = 3 different brands of 60-watt soft-white lightbulbs, with J = 8 bulbs of each brand tested. The sums of squares were computed as SSE = 4773.3 andSSTr = 591.2. State the hypotheses of interest (in- cluding word de nitions of parameters), and use the F test of ANOVA (a = .05) to decide whether there are any differences in true average lumen outputs among the three brands for this type of bulb by obtaining as much information as possible about the P-value.
