Question

A certain genetic characteristic of a particular plant can appear in one of three forms (phenotypes). A researcher has developed a theory, according to which the hypothesized proportions are p1 = .25, p2 = .50, and p3 = .25. A random sample of 200 plants yields 2 = 5.45.

(a) Carry out a test of the null hypothesis that the theory is correct, using level of significance = .05. (Round your answer to three decimal places.)
P-value =  

What can you conclude?

There is sufficient evidence to reject H0.There is insufficient evidence to reject H0.    

(b) Suppose that a random sample of 300 plants had resulted in the same value of 2. How would your analysis and conclusion differ from those in Part (a)?

The previous analysis did not yield a significant result and the null hypothesis failed to be rejected. The new analysis would yield a significant result and the null hypothesis would be rejected.The previous analysis yielded a significant result and the null hypothesis was rejected. The new analysis would not yield a significant result and the null hypothesis would fail to be rejected.    The analysis and conclusions would not change.

Explanation / Answer

p value is 1

There is insufficient evidence to reject H0

The previous analysis didnot yield a significant result and the null hypothesis failed to be reject. The new analysis would yield a significant result and the null hypothesis wouldbe reject
