A consumer product magazine recently ran a story concerning the increasing prices of digital cameras. The story stated that digital camera 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 digital cameras a couple of years ago was $215.00. A random sample of n = 22 cameras was recently taken and entered into a spreadsheet. It was desired to test to determine if that average price of all digital cameras is now more than $215.00. Find a rejection region appropriate for this test if we are using α = 0.05.
◦ Reject H0 if t > 2.080 or t < -2.080
◦ Reject H0 if t > 1.717
◦ Reject H0 if t > 1.725
◦ Reject H0 if t > 1.721
