Question
tak Aplia: Student Question udent believes thait people consider faces with more contrast bebween lip color and e identifies the null and alternative hypotheses as: I of contrast between lip color and skin tone does not affect how feminine a face is considere I of contrast between lip color and skin tone affects how feminine a face is considered. a significance level of.01. After she collects the data and computes the sample statistics, it i a dedision about Ho. graduate student can make given her choices of Ho and Ha. o possible decisions that the is enough evidence minine a face is considered is not enough evidence to reject the hypothesis that the contrast between lip color and skin fect how feminine a face is considered is not enough evidence to eminine a face is considered is enough evidence to reject the hypothesis that the contrast between lip color and skin tons to reject the hypothesis that the contrast between lip color and skin tons reject the hypothesis that the contrast between lip color and skin how feminine a face is considered. should the graduate student make if the test statistic is in the critical region? aduate student should reject the null hypothesis. aduate student cannot reject the null hypothesis. aduate student should reject the alternative hypothesis the test statistic is 3.25 and the boundary to the critical region is 2.576. The test statistic is gion. Therefore, the graduate student the level of contrest between lip color and skin tone affects how feminine a face is considere reject the null hypothesis, and she the Distributions tool if you find it helpful.
Explanation / Answer
test statistic=3.25
critical value=2.576
test statistic>critical value
Reject null hypothesis
graduate student has to reject thenull hypothesis
