You are trying to find the average age of trees in Muir Woods. Someone claims the average of trees is 20 years, but you think it's older. In order to test, you take a sample size of 10 trees. The computed value of the sample average is 22 years. The underlying distribution of trees ages is assumed to be normal and stardard deviation is assumed known at 3 years.  Perform this test at the alpha=.1 level. Compute the test statistic for this test. Round to the nearest thousandth.
