A psychologist wants to determine whether a new mindfulness training program improves reaction time. The table below shows the reaction times (in milliseconds) for 1010 participants before and after completing the program:At the α=0.05\alpha = 0.05 significance level, is there sufficient evidence to support the psychologist’s claim that the training program reduces reaction time?

Problem 27Multiple Choice

A psychologist wants to determine whether a new mindfulness training program improves reaction time. The table below shows the reaction times (in milliseconds) for $10$ participants before and after completing the program:

At the $alpha equals 0.05$ significance level, is there sufficient evidence to support the psychologist’s claim that the training program reduces reaction time?

There is insufficient evidence to support the claim that the training program reduces reaction time.

There is sufficient evidence to support the claim that the training program reduces reaction time.

The training program increases reaction time significantly.

There is no difference in reaction time before and after the training program.
