Question: A Michigan automobile insurance company would like to estimate the average size of an accident claim for the fiscal year 2009. A random sample of 20 accidents claims yielded an average of $1600 with a standard deviation of $800. The national average claim for the industry is $1500. Does the sample indicate that the Michigan average is different from the national average? Use alpha =.10

State the hypothesis, the test statistic, the conclusion, (what you are accepting or rejecting) and make sure you answer the question.
