An associate at a large home improvement store claims that she can build a composite 12 × 20-foot deck for an average cost of $7200. We sample eight decks built by this associate and find that their average cost was $8215.22 with a standard deviation of $711.16. Does it appear from this sample that the claim of $7200 is not accurate (either too high or too low)? State the critical value (CV), test statistic (TS), and decision from the test. (Use α = 0.05.)
