(You may find it useful to reference the q table.) Hybrid 1: 21 = 30, n1 = 20 Hybrid 2: 202 = 42, n2 = 15 Hybrid 3: 23 = 29, n3 = 18 Source of Variation SS df MS F p-value Between Groups 1, 032. 24 2 516.12 18.34 0.0000 Within Groups 1, 407 . 06 50 28.14 Total 2, 439.30 52Population Mean Can we conclude that the Differences Confidence Interval hybrids' means differ?
