Derek sells baked goods at the local farmers market and he has been charging $2 per cupcake because hefeels that is the average going price for cupcakes. He wants to make sure that he isn't losing customers byoverpricing or shorting himself out of extra profit. He surveys a number of sellers to see if he is charging theright amount and wants to use a 5% significance level to confirm his results.

If Derek were to conduct this test, what significance level would indicate that his null hypothesis, stating that the average cupcake price of $2, should be rejected?
