A graduate student beleves that people consider faces with more contrast between lip color and skin tone as more feminine. He identifies the nul and alternative hypotheses as: He: The level of contrast between ip calor and skin tone does not affect how feminine a face is considered. Ha: The level of contrast between lip color and skin tone affects how feminine a face is considered. He chooses a significance level of 0.05. After he collects the data and computes the sample statistics, R is time for him to make a decision about Ha. Check the two possitle decislons that the graduate studert can make given his choices of Ho and H. Check all that apply. O There is not enough evidence to reject the hypothesis that the contrast between ip color and skin tone does not affect how feminine . face is considered. O There is enough evidence to reject the hypothesis that the contrast between lip color and skin tone does not afect how feminine a face is considered. O There is enough evidence to reject the hypothesis that the contrast between lip color and skin tone affects how feminine a face is considered. O There is not enough evidence to reject the hypothesis that the contrast between ip color and skin tone affects how feminine a face is considered. What decislon should the graduate student make if 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 null hypothesis. Suppose that the test statistic is 2.59 and the boundary to the critical region is 1.96. The test statistic is the critical region. Therefore, the graduate student reject the null hypothesis, and he conclude that the level of contrast between lp color and skin tone affects how feminine a face is considered.

A graduate student believes that people consider faces with more contrast between lip color and skin tone as more feminine. He identifies the null and
alternative hypotheses as:
Ho: The level of contrast between lip color and skin tone does not affect how feminine a face is considered.
Hi: The level of contrast between lip color and skin tone affects how feminine a face is considered.
He chooses a significance level of 0.05. After he collects the data and computes the sample statistics, it is time for him to make a decision about Ho.
Check the two possible decisions that the graduate student can make given his choices of Ho and Hı. Check all that apply.
