Yes or no? In Example 8.4 we performed a significance test to compare your product with your competitor’s. Successwas defined as the outcome where your product provided better protection. Now, take the viewpoint of your competitor and define success as the outcome where your competitor’s product provides better protection. In other words, n remains the same (20) 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 8.4?

(b) Find the 95% confidence interval for this setting and compare it with the interval calculated where success is defined as the outcome when your product provides better protection.
