Janiceis a fashion designerwho wondered garments in vibrant colors attracted more attention in stores thanmuted colors. To test this theory, Janiceduplicated all of her garments with vibrant colorsto be inmuted colors and duplicated all of her garments in muted colors be in vibrant colors. During one weekend in a pop-up store, she randomly selected garments to show on Saturdayand showed the color-switched garments on Sunday. She used the security footage to find the average time people looked at each of her10

garments. Assume that both of the populations are normally distributed.

She tests the paired data, where=0.05

To evaluate the claim that the true mean difference in the times between the black and white paintings and the color paintings is significantly different from zero.

She used the security footage to find the average time people looked at each of her 10 garments. Assume that both of the populations are normally distributed. She tests the paired data, where a = 0.05, in order to evaluate the claim that the true mean difference in the times between the black and white paintings and the color paintings is significantly different from zero. For this test: Ho : Ma = 0, Ha : Ma # 0, which is a two-tailed test. The test results are: t ~ -4.755 , p-value is approximately 0.001 Which of the following are appropriate conclusions for this hypothesis test? Select all that apply. Select all that apply: Reject the null hypothesis that the true mean difference in the times between the muted colors and vibrant colors is equal to zero. Fail to reject the null hypothesis that the true mean difference in the times between the muted colors and vibrant colors is equal to zero. There is sufficient evidence at the a = 0.05 level of significance to suggest that the true mean difference in the times between the muted colors and vibrant colors is significantly different from zero. There is insufficient evidence at the a = 0.05 level of significance to suggest that the true mean difference in the times between the muted colors and vibrant colors is significantly different from zero.
