2. In a study of absolute errors in active versus passive arm positioning, an investigator collected data (in centimeters) on 20 college-age subjects (from the motor learning laboratory, California State University Northridge, courtesy of Tami Abourezk). Does a significant difference exist in the errors in arm positioning made by the active group (N1 = 10) compared with those made by the passive group (N2 = 10), Calculate the Paired t-test for the two groups. • Group One Active Positioning: 2.65, 2.42, 3.30, 0.19, 1.25, 2.0, 3.34, 4.08, 0.70, 2.89 • Group Two Passive Positioning: 3.30, 2.00, 0.09, 0.04, 4.56, 3.33, 1.02, 0.89, 2.78, 1.65 Provide the following information: The two-tailed P value, The mean of Group 1 and Group 2, Standard Deviation, and Standard Error of Mean for each group. Answer the following question: Does a significant difference exist in the errors in arm positioning made by the Active Group compared with those made by the Passive Group. Support your answer.
