Random samples of four different models of cars were selected and the gas mileage of each car was measured. The results are shown below. Model A / Model B / Model C / Model D 20 / 22 / 23 / 21 22 / 20 / 23 / 21 22 / 21 / 23 / 22 21 / 21 / 24 / 22 Test the claim that the four different models have the same population mean. Use a significance level of 0.05. Use the p-value method of hypothesis testing. Enter the p-value. (Round your answer to nearest thousandth.)
