According to a certain Mendelian genetic model, self-pollination of pink-flowered plants should produce progeny that are red, pink, and white in the ratio 1:2:1. A geneticist self-pollinated pink-flowered snapdragon plants and produced 234 progeny with 54 red, 122 pink and 58 white flowered plants. To test if these numbers indeed follow the model ratio, what should be an appropriate null hypothesis? A. P(Red) = 54/234, P(Pink) = 122/234, P(White) = 58/234. B. P(Red) = 54%, P(Pink) = 122%, P(White) = 58%. C. P(Red) = 1, P(Pink) = 2, P(White) = 1. D. P(Red) = 0.25, P(Pink) = 0.5, P(White) = 0.25. 2. What would be the degree of freedom for an appropriate test? A. 3 B. 2 C. 1 D. 0 3. If we fail to reject the null hypothesis at 0.05 significance level, what do you conclude? A. The self-pollinated plants of the geneticist do not follow the ratio 1:2:1 and this validates the model. B. The self-pollinated plants of the geneticist do not follow the ratio 1:2:1 and this contradicts the model. C. The self-pollinated plants of the geneticist indeed follow the ratio 1:2:1 and this validates the model. D. The self-pollinated plants of the geneticist indeed follow the ratio 1:2:1 and this contradicts the model.

1. According to a certain Mendelian genetic model, self-pollination of pink-flowered plants should produce progeny that are red, pink, and white in the ratio 1:2:1. A geneticist self-pollinated pink-flowered snapdragon plants and produced 234 progeny with 54 red, 122 pink and 58 white flowered plants. To test if these numbers indeed follow the model ratio, what should be an appropriate null hypothesis?

A. P(Red) = 54/234, P(Pink) = 122/234, P(White) = 58/234.

B. P(Red) = 54%, P(Pink) = 122%, P(White) = 58%.

C. P(Red) = 1, P(Pink) = 2, P(White) = 1.

D. P(Red) = 0.25, P(Pink) = 0.5, P(White) = 0.25.

2. What would be the degree of freedom for an appropriate test?

A. 3

B. 2

C. 1

D. 0

3. If we fail to reject the null hypothesis at 0.05 significance level, what do you conclude?

A. The self-pollinated plants of the geneticist do not follow the ratio 1:2:1 and this validates the model.

B. The self-pollinated plants of the geneticist do not follow the ratio 1:2:1 and this contradicts the model.

C. The self-pollinated plants of the geneticist indeed follow the ratio 1:2:1 and this validates the model.

D. The self-pollinated plants of the geneticist indeed follow the ratio 1:2:1 and this contradicts the model.
