8.40 Should a one-sided or a two-sided test be performed? Why? 8.41 Perform the test in Problem 8.40, and report a p-value. 8.42 Compute a 95% CI for the true mean difference between observers. How does it relate to your answer to Problem 8.41? 8.43 Suppose the results of Problem 8.41 show no significant difference. Does this mean this type of assessment is highly reproducible?
