Question: suppose a sample of 49 paired differences that have been...

Question details

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 and a sample standard deviation of sd-7. (a) Calculate a 95 percent confidence interval for μο μι-P2. (Round your answers to 2 decimal places.) Confidence interval 2.989 7011 (b) Test the null hypothesis Ho: μ.-0 versus the alternative hypothesis Ha: Ha ? 0 by setting ? equal to 10, 05, 01, and .001. How much evidence is there that μd differs from 0? t- 5 Reject Ho at ? equal to 0.1 and 0.001 extremely strong : evidence that μ1 differs from P2 c) The p value for testing Ho μ4S 3 versus Ha μd> 3 equals 0.0256 Use the p-value to test these hypotheses with ? equal to say about the size of the difference between μ1 and μ27(Round your p-value answer to 4 decimal places.) 10, 05, 01, and .001. How much evidence is there that μ xceeds 3? What does this p0.0256 Reject HO at ?equal to Click to select ; Click to select evidence that μ, and μ2 differ by more than 3
