Chapter 10.2, Problem 60E

(a)

To determine

To explain: whether paired t test or two-sample t test should be used to conduct inference on the basis of the information provided.

Answer to Problem 60E

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 has a littermate in another sample

(b)

To determine

To explain: whether paired t test or two-sample t test should be used to conduct inference on the basis of the information provided.

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 determine

To explain: whether paired t test or two-sample t test should be used to conduct inference on the basis of the information provided.

Answer to Problem 60E

Two-sample t procedures

Explanation of Solution

If in the other sample, a value in one sample has a similar value, paired t procedures are used, otherwise the two-sample t procedures are used.

Two-sample t procedures

Since each sample involves multiple subjects
