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 alternative hypotheses as: H₁: The level of contrast between eye color and skin tone does not affect how feminine a face is considered. H₁: The level of contrast between eye color and skin tone affects how feminine a face is considered. She chooses a significance level of 0.01. After she collects the data and computes the sample statistics, it is time for her to make a decision about H₂ Check the two possible decisions that the graduate student can make given her choices of H, and H₂. Check all that apply. 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. 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 does not affect how feminine a face is considered. What decision should the graduate student make if the test statistic is not inside the critical region? O The graduate student should reject the null hypothesis. The graduate student should reject the alternative hypothesis. The graduate student cannot reject the null hypothesis.
