You suspect this claim is incorrect and find that a random sample of 15 similar vehicles has a mean price of $18.550 and a standard deviation of $1767. Is there enough information to reject this claim at o = 0.02? Assume the population of used car prices is normally distributed. STEP 1: Identify the hypothesis statements, state which hypothesis is the claim, and the type of test you need to complete (left-, right-, two-tail). Ho: STEP 2: State the significance level. Determine the Rejection Region Critical Boundary Value(s): STEP 3: Calculate the appropriate standardized test statistic (two decimal places) and the associated p-value (three decimal places). Test Statistic: P-value:STEP 4: Conclusion, your conclusion must include supporting evidence. Comparison (P-value
