Matched or Paired Samples (Optional) · Exercise 33

Indicate which of the following choices best identifies the hypothesis test.

A new SAT study course is tested on 12 individuals. Pre-course and post-course scores are recorded. Of interest is the mean increase in SAT scores. The following data are collected:

$$\begin{array}{cc}\text{Pre-course score}& \text{Post-course score}\\ \text{1}& \text{300}\\ \text{960}& \text{920}\\ \text{1010}& \text{1100}\\ \text{840}& \text{880}\\ \text{1100}& \text{1070}\\ \text{1250}& \text{1320}\\ \text{860}& \text{860}\\ \text{1330}& \text{1370}\\ \text{790}& \text{770}\\ \text{990}& \text{1040}\\ \text{1110}& \text{1200}\\ \text{740}& \text{850}\end{array}$$

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
