Question: Farm Sizes: Ten years ago, the average acreage of farms in a certain geographic region was 65 acres. The standard deviation of the population was 7 acres. A recent study consisting of 22 farms showed that the average was 63.2 acres per farm. Test the claim, at α = \(0.10\), that the average has not changed by finding the P-value for the test. Assume that standard deviation has not changed and the variable is normally distributed.
