Suppose a sample of 49 paired differences that have been randomly selected from a normally distributed population of paired differences yields a sample mean of d 5.2 and a sample standard deviation of sg=7.4. (a) Calculate a 95 percent confidence interval for Hd H₁-H₂ (Round your answers to 2 decimal places.) Confidence interval- (b) Test the null hypothesis Ho Hd=0 versus the alternative hypothesis Ha Hd O by setting a equal to 10, 05, 01, and .001. How much evidence is there that a differs from 0? evidence that ut differs from 12. Reject HO at a equal to (c) The p-value for testing He Hd 3 versus Ho Ha> 3 equals 0.0214. Use the p-value to test these hypotheses with a equal to 10, 05, 01, and 001. How much evidence is there that exceeds 3? What does this say about the size of the difference between and µ₂? (Round your p-value answer to 4 decimal places.) Reject HO at a equal to evidence that u1 and u2 differ by more than 3
