Can someone help me understand how to do a F-test on these two data tables. I already calculated variance, I just need help with Anova and finding the F-value and F-critical.

\fHeight (whole ID inches) Xi - x (xi - x) 2 60 -7.740740741 59.91906722 60 -7.740740741 59.91906722 60 -7.740740741 59.91906722 4 62 -5.740740741 32.95610425 5 63 -4.740740741 22.47462277 64 -3.740740741 13.99314129 65 -2.740740741 7.511659808 8 66 -1.740740741 3.030178326 LO 66 -1.740740741 3.030178326 10 66 -1.740740741 3.030178326 11 67 -0.7407407407 0.548696845 12 67 -0.7407407407 0.548696845 13 68 0.2592592593 0.06721536351 14 68 0.2592592593 0.06721536351 15 68 0.2592592593 0.06721536351 16 69 1.259259259 1.585733882 17 70 2.259259259 5. 104252401 18 70 2.259259259 5.104252401 19 70 2.259259259 5. 104252401 20 70 2.259259259 5. 104252401 21 71 3.259259259 10.62277092 22 72 4.259259259 18. 14128944 23 72 4.259259259 18. 14128944 24 72 4.259259259 18. 14128944 25 74 6.259259259 39.17832647 26 74 6.259259259 39.17832647 27 75 7.259259259 52.69684499 HEIGHT: 485.1851852 TOTAL Mean: 67.74074074 18.66096866 485.1851852/26 Variance: 18.66096866 Std.
