Question 5 (Chi-square monohybrid cross)

In an experiment with pea plants starting from two true-breeding lines (one with smooth seeds and the other with wrinkled seeds), an $F_2$ generation gave the following counts: 684 plants with smooth seeds and 198 with wrinkled seeds. Under the null hypothesis of a standard monohybrid cross with full dominance of smooth over wrinkled seeds, the calculated $\chi^2$ value yields a $p$-value between:
