A graduate student beleves that people consider faces with more contrast between lip color and skin tone as more feminine. He identties the null and alternative hypotheses as: He: The level of contrast between lip color and skin tone coes not affect how feminine a tace is considered. Hi: The level of contrast between lip color and skin tone affects how feminine a face is considered. He chooses a signficance level of 0.05. After he collects the cata and computes the sample statstics, is time for him to make a decision about He. Check the two possitie decisions that the graduate student can make given his choices of Ho and H. Check al that apply. O There is not enough evidence to reject the hypothess that the contrast between ip color and skin tone does not affect how feminine a face is considered. O There is enough evidence to reject the hypothesis that the contrast between lp color and skin tone coes not affect haw feminine a face is considered. O There is enough evidence to reject the hypothesis that the contrast between lp color and skin tone affects how feminine a face is considered. O There is not enough evidence to reject the hypothess that the contrast between ip color and skin tone affects how feminine a face is considered. What decision should the graduate student make r the test statistic is not inside the critical region? O The graduate student cannot reject the null hypothesis. O The graduate student should reject the alternative hypothesis. O The graduate student should reject the nul hypothesis. v the critical region. Therefore, the v condude that the level of contrast between lip color and skin tone Suppose that the test statistic is 2.59 and the boundary to the oritical region is 1.96. The test statistic is graduate student v reject the null hypothesis, and he affects how feminine a tace is considered. You may use the Dutritutions tool you find it heipful. Sandad N tian 0.674
