Show transcribed image text A study was conducted to determine whether magnets are effective at treating back pain. The results are given in the table. Use a 0.05 significance level to test the claim that those treated with magnets have greater reduction in pain x than those given a sham treatment (similar to a placebo). Do not assume the population standard deviations are equal. Does it appear magnets are effective in treating back pain? 26 26 x 0.580.55 0.97 0.99 Click the icon to view the table of critical values. Choose the correct answer below. A. O B. C. No, because the null hypothesis is not rejected. Yes, because the null hypothesis is not rejected. No, because the null hypothesis is rejected. 0 D. Yes, because the null hypothesis is rejected.
