Document Summary
Chapter 25: comparing two population means paired. The blood pressure of five patients were recorded before and 30 minutes after receiving a drug. The results are given in the following table. The difference between independent and dependent samples, Hypothesis tests for a matched pairs design, for a matched pairs design: let d y. Inference about d = average of d-values ds = standard deviation of d-values. 1 is given by: d t ds n. Example 25. 1: two computers often are compared by running a collection of different benchmark"" programs and recording the difference in cpu time required to complete the same program. Six benchmark programs, run on two computers, produced the following cpu times (in minutes): Computer 2 (a) find a 99% confidence interval for the difference in mean cpu time required for the two computers to complete a job. Solution: (b) does the data provide sufficient evidence to indicate that the mean.
