(a)
To explain: whether paired t test or two-sample t test should be used to conduct inference on the basis of the information provided.
(a)
Answer to Problem 59E
Two-sample t procedures
Explanation of Solution
If in the other sample, each value in one sample has a associating value, it use paired t procedures, otherwise it use two-sample t procedures.
Two-sample t procedures
Since they contain different tyres in each sample.
(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 59E
Paired t procedures
Explanation of Solution
If in the other sample, of value in one sample has a associating value, then it use paired t procedures, otherwise the two-sample t procedures are used.
Paired t procedures.
Since every subject is in both samples.
(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 59E
Two-sample t procedures
Explanation of Solution
If in the other sample, of value in one sample has a corresponding value, then we use paired t procedures, otherwise the two-sample t procedures are used.
Two-sample t procedures
Since each sample includes numerous subjects
