To assess Mendel's law of segregation using tomatoes, a true-breeding tall variety (SS) is crossed with a true-breeding short variety (ss). The heterozygous F₁ tall plants (Ss) were crossed to produce two sets of F₂ data, as follows. Set I Set II _ 30 tall 300 tall      5 short      50 short Using the X² test, analyze the results for both datasets. Calculate X² values and estimate the p values in both cases.
