Question

A poony plant with red petals was crossed with another plant having streaky petals. A geneticist states that 75% of the offspring resulting from this course will have red flowers To test this claim, 100 seeds from this cross were collected and germinated, and 58 plants had rod petals What is the rejection region? Reject Ho if Z > 2.326 Reject Ho if Z 2.576 Reject H0 if Z 1.96 A poony plant with red petals was crossed with another plant having streaky petals. A geneticist states that 75% of the offspring resulting from this course will have red flowers To test this claim, 100 seeds from this cross were collected and germinated, and 58 plants had rod petals What is your decision? Both reject and fail t reject H0 Reject H0 fail to reject H0 Reject Ha

Explanation / Answer

For a right tailed test, the critical region at alpha=0.05 is 1.96.

option 4)

4. Compute 1-proportion Z test.

Z=(Ps-Pu)/sqrt [Pu(1-Pu)/N]

=(58/100-0.75)/sqrt[0.75(1-0.75)/100]

=-6.8

The test statistic do not fall in critical region, therefore, fail to reject H0.
