Two fuel additives are being tested to determine their effect on gasoline mileage. Seven cars were tested with additive 1 and seven cars were tested with additive 2. The following data show the miles per gallon obtained with the two additives. Additive 1 Additive 2 17.3 18.7 18.4 17.8 19.1 21.2 16.7 21.1 18.2 22.1 18.6 18.7 17.5 19.7 Use a = 0.05 and the MWW test to see whether there is a significant difference between gasoline mileage for the two additives. Use Table 1 of Appendix B. What is the mean and standard deviation of the normal distribution that can be used for this statistical test? Mean -1.92 (to 1 decimal) Standard deviation 6.6740 (to 4 decimals) What is the value of the test statistic (to 2 decimals)? Enter negative value as negative number. -1.92 What is the p-value for the hypothesis test (to 4 decimals)?
