1a. The One-Sample T-Test Procedure: Test the difference between a sample mean and a known or hypothesized value (Small N). (2 pts total) Problem: A pizza company in Storrs claims in an advertisement that customers will get their order within 30 minutes. A competitor wants to test this claim, trying to prove that the average time for delivery is over 30 minutes. A random sample of 20 delivery times is collected: Xi = 39, 35, 37, 28, 40, 25, 27, 24, 42, 45, 20, 38, 39, 25, 42, 26, 48, 51, 48, 41 Does the competitor have evidence to suggest the 30-minute delivery time is false? Step 1: 3 Assumptions (.20 pts.) Random sample Step 2: Hypothesis (.40 pts.) HO: U 30 Two tail Step 3: Define the Test Statistic (T-critical, one tail test) (.40 pts.) This will be up to the student depending on their taste for Type I Error: (e.a : a critical
