Hurricane Andrew swept through southern Florida causing billions of dollars of damage. Because of the severity of the storm and the type of residential construction u in this semitropical area, there was some concern that the average claim size would be greater than the historical average hurricane claim of $25,500. Several insuran companies collaborated in a data gathering experiment. They randomly selected 22 homes and sent adjusters to settle the claims. In the sample of 22 homes, the average claim was $28,000 with a population standard deviation of $5700. Is there sufficient evidence at a 0.05 significance level to support the claim that the home damage is greater than the historical average? Assume the population of insurance claims is approximately normally distributed. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.
