13. The decision-making process Aa Aa A graduate student believes that people consider faces with more contrast between eye color and skin tone as more feminine. She identifies the null and altemative hypotheses as: Hp: The level of contrast between eye color and skin tone does not affect how feminine a face is considered Hi: The level of contrast between eye color and skin tone affects how feminine a face is considered She chooses a significance level of .05. After she collects the data and computes the sample statistics, it is time for her to make a decision about Ho Check the two possible decisions that the graduate student can make given her choices of Ho and Hi There is not enough evidence to reject the hypothesis that the contrast between eye color and skin tone does not affect how feminine a face is considered There is enough evidence to reject the hypothesis that the contrast between eye color and skin tone does not affect how feminine a face is considered There is not enough evidence to reject the hypothesis that the contrast between eye color and skin tone affects how feminine a face is considered There is enough evidence to reject the hypothesis that the contrast between eye color and skin tone affects how feminine a face is considered What decision should the graduate student make if the test statistic is in the critical region? O The graduate student cannot reject the null hypothesis. O The graduate student should reject the altemative hypothesis. O The graduate student should reject the null hypothesis. Suppose that the test statistic is 1.08 and the boundary to the critical region is 1.960. The test statistic is the critical region. Therefore, the graduate student conclude that the level of contrast between eye color and skin tone affects how feminine a face is conside reject the null hypothesis, and she not in

Explanation / Answer

Possible decisions for H0 And H1 are as:

Option a) and option d)

If the test statistic is in the critical region the graduate student cannot reject the null hypothesis

The test statistic is in the critical region.

Therefore, the graduate student cannot reject the null hypothesis.
