Multiple Choice

Exhibit 7-4: A group of researchers has developed a method that they hypothesize will improve physics test scores.They randomly selected nine students to participate in their study.The nine students were administered an ACT test, trained in the new method, and then administered an alternate form of the ACT test.The following data are their scores:
$\begin{array}{lll}\text {Subject } & {\text {Test 1 }}{} & \text {Test 2 } \\ 1 & 20 & 19 \\ 2 & 20 & 20 \\ 3 & 24 & 21 \\ 4 & 24 & 24 \\ 5 & 24 & 22 \\ 6 & 17 & 15 \\ 7 & 18 & 15 \\ 8 & 18 & 16 \\ 9 & 20& 18\end{array}$
-Refer to Exhibit 7-4.The researchers can conclude that:

• A) there is no statistically significant evidence that students who use the new ACT training will improve their ACT scores.
• B) the evidence suggests the new training improves ACT scores.
• C) the evidence suggests the new ACT training decreases ACT scores.
• D) none of these are true.
