(b)
To explain: whether paired t test or two-sample t test should be used to conduct inference on the basis of the information provided.
(b)
Answer to Problem 60E
Two-sample t procedures
Explanation of Solution
If a value in one sample has a related value in the other sample, then paired t procedures are used, otherwise the two-sample t procedures are used.
Two-sample t procedures
Since each sample includes numerous subjects
(c)
To explain: whether paired t test or two-sample t test should be used to conduct inference on the basis of the information provided.
(c)
Answer to Problem 60E
Two-sample t procedures
