8.9 Redefining success: In Example 8.5 (page 491) , we performed a sig nificance test t0 compare your product with your competitors Success defined as the outcome where your product provided was better protection; Now; take the viewpoint of your competitor where success is defined to be the outcome where your competitors product provides better protection In other words, n remains the same, but X is now 7. (a) Perform the two-sided significance test and report the results: How do these compare with what we found in Example 8.5? (b) Find the 95% confidence interval for this setting, and compare it with the interval calculated when success is defined as the outcome where your product provides better protection.
