Pic is not clear. Please pardon . Repost if I have taken different value. Otherwise you can solve this question in following manner
hypothesis statements , given in option A is correct.
Actual Values:
39 21 15
23 26 11
25 33 16
Expected Values:
31.2201 28.7081 15.0718
24.9761 22.9665 12.0574
30.8038 28.3254 14.8708
Chi-Squared Values:
1.93872 2.06963 0.000341763
0.156345 0.400674 0.0927337
1.09351 0.771474 0.0857426
Chi-Square = 6.60917
Degrees of Freedom = 4
p = 0.15804
Here P value is greater than 0.05 hence we can not reject null hypothesis. It means that both variable are independent. option B is correct.

A genetic experiment involving peas yielded one sample of offspring consisting of 449 green peas and 162 yellow peas. Use a 0.01 significance level to test the claim that under the same circumstances, 26% of offspring peas will be yellow.
