A consumer product magazine recently ran a story concerning the increasing prices of CINCO-FONES. The story stated that CINCO-FONE prices dipped a couple of years ago, but now are beginning to increase in price because of added features. According to the story, the average price of all CINCO-FONES a couple of years ago was $215.00. A random sample of n = 22 CINCO-FONES was recently taken and entered into a spreadsheet. It was desired to test to determine if that average price of all CINCO-FONES is now more than $215.00. Find a rejection region appropriate for this test if we are using α = 0.05.
