The following output summarizes the results for a one-way analysis of variance experiment in which the treatments were three different hybrid cars and the variable measured was the miles per gallon (mpg) obtained while driving the same route. (You may find it useful to reference the q table.) Hybrid 1: 1 = 33, m1 = 20 Hybrid 2: 1 = 44, no = 15 Hybrid 3: 13 = 37, 03 = 18 Source of Variation SS MS F p-Value Between Groups 1, 082.38 2 541. 19 19.38 9. 0900 within Groups 1, 395.94 50 27.92 Total 2, 478. 32 52 a. At the 1% significance level, can we conclude that average mpg differs between the hybrids? Yes. since the p-value is less than the significance level. Yes, since the p-value is not less than the significance level. No, since the p-value is less than the significance level. O No, since the p-value is not less than the significance level.b. Use Tukey's HSD method at the 1% significance level to determine which hybrids' means differ. (If the exact value for nT - c is not found in the table, then round down. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) Population Mean Can we conclude that the Differences Confidence Interval hybrids' means differ? H1 = H2 -16.52 -5.48 Yes -9.25 1 No H2 - Ha 12.65 Yes
