Claire knows the z score for her research hypothesis is -2.05, and her critical values are -1.96 and 1.96 for an alpha value of 0.05. What should she conclude about her hypothesis given these statistics?

	a.	She should reject the null hypothesis and report the direction of the effect because the score is in a critical region (below -1.96).
	b.	She should reject the null hypothesis but not report the direction of the effect because she doesn't have enough information.
	c.	She should fail to reject the null hypothesis because the score is not in a critical region (above 1.96 or below -1.96).
	d.	She should fail to reject the null hypothesis because she doesn't have enough information.

Expert Solution

Option-A) She should reject the null hypothesis and report the direction of the effect because the score is in a critical region (below -1.96).

Because z score is less than critical value
