3. Police trainees were seated in a darkened room facing a projector screen. Ten different license planes were projected on the screen, one at a time, for 5 seconds each, separated by 15-second intervals. After the last 15-second interval, the lights were turned on and the police trainees were asked to write down as many of the 10 license plate numbers as possible, in any order at all. A random sample of 10 trainees who took this test where then given a week-long memory training course. They were then retested. The results are shown in the table below. After Before Person Training Training 6. 8 7 6. 4 5 5 9 7 8. 6. 8 6. 9 4 10 2 Do these results provide evidence that the memory course improved the ability of the trainees to correctly identify license plates? Use a 0.05 level of significance. (Use After – Before.)
