Answer 1

Answer Giver that A psychology class performed an experiment to compare whethel a recell scale in which instructions to fom images of 25 words were given is better than as initial recall scale for which no imaginary instructions w e given The mean and standud devictions of the difference measuren ove d = 10.25 So=4.051 and =20. The gull and alternative hypothesis are: Ho.l- o versus Hailu-M, 70 The test stilistic is neafurements Salin t = 1025-0 4.051 To t = 1025 0.906 t = 11-316. since the value t = 11.316 with of = n-1 = 19 lies above +0.005 = 2.861, the tail area to the right of 11.316 is below 0.005 p-value 20.005. Since the P-velue is very low we can reject to and conclude that there is sufficient evidence to indicate that the average recall score is higher when imagery is used.
