Question

A certain genetic characteristic of a particular plant can appear in one of the forms Cohen types). A researcher has developed a theory according to which the hypothesized proportions are P, -0.25.-6.50, and "0.25. A random sample of 200 plant yields x2.5.15. (a) Carry out a best of the null hypothesis that the theory is correcting level of significance 0.05. What the critical value for the test round your answer to two decimal places) Critical Value State the conclusion in the problem context O Fall to reject. There is not convincing evidence that the researcher's theory is incorrect O Reject Mg.There not convincing evidence that the researchers theory is incorrect O Reject There is convincing evidence that the researcher's theory to incorrect O Fail to reject Hy. There is convincing evidence that the researcher's theory incorrect (b) Suppose that a random sample of 300 plants had resulted in the same value of x. How would your analysis and conclusion offer from those in part (a)? The previous analysis yielded a significant result and the hul hypothes wat rejected. The new analysis would not yield significant res and the null hypothesis would has to be rejected The analysis and conclusion would not change The previous analysis did not yield significant result and the wall hypothesis failed to be rected. The best any would yield can rest and the null hypothesis would be rejected

Answer 1

sal: (a) Degree of freedom - 3-1 = ၃ Q=0.05 The critical value = 5.99 since - 5.15 is less the Critical value. x calculated fail to reject Ho. So, we option (A) is carrect. (b) option (B) is correct.
