During a typical Professional Golf Association (PGA) tournament, the competing golfers play four rounds of golf, where the hole locations are changed for each round. Here are the scores for the top five finishers at the 2009 U.S. Open.

The following statistics were computed:
SST = 272.95 SSB = 93.2 SSE = 127.6
a. Construct the ANOVA table.
b. At the 5% significance level, can you conclude that the average scores produced by the four different rounds differ?
c. At the 5% significance level, can you conclude that the average scores produced by the five different players differ?
