(You may find it useful to reference the g table.) Exercise 13-23 Algo Hybrid 1: XI = 33, n1 = 20 Hybrid 2: 2 = 45, n2 = 15 Hybrid 3: 23 = 39, n; = 18 Source of variation .93 df MS F pValue Between Groups 1,080.89 2 540.45 20.48 0.0000 Within Groups 1:319.63 50 26.39 Total 2,400.52 52 a. At the 5% significance level, can we conclude that average mpg differs between the hybrids? Yes. since the pvalue is less than the significance level. 9 Yes. since the pvalue is not less than the significance level. No.5ince the pvalue is less than the significance level. No.5ince the pvalue is not less than the significance level. b. Use Tukey's HSD method at the 5% significance level to determine which hybrids' means differ. (If the exact value for an. - cis not found in the table, then round down. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) 0 Answer is complete but: not: entirely correct. Population Men Can we conclude that the Condence Interval hybrids' means differ? 'Fz
