Muscles flex when stimulated through electric impulses either to motor points (points on the muscle) or to nerves. The article Force Assessment of the Stimulated Arm Flexors: Quantification of Contractile Properties (J. Hong and P. laizzo, Journal of Medical Engineering and Technology, 2002:28-35) reports a study in which both methods were applied to the upper-arm regions of each of several subjects. The latency time (delay between stimulus and contraction) was measured (in milliseconds) for each subject. The results for seven subjects are presented in the following table. Subject 1 2 3 4 5 6 7 Mean SD Nerve 59 58 38 53 47 51 51.86 7.45 Motor Point 56 52 56 32 47 42 48 47.57 8.52 Difference 3 2 6 6 3 4.29 1.60 Can you conclude that there is a difference in the latency period between motor points and nerve stimulation? Assume all conditions are satisfied and test at the o = 10% level. To answer this question, do the following: Compute the test statistic (Round to two decimal places). Choose the correct critical value to compare your test statistics to: (only input the number, e.g. 1.44 ) t.10, df = 6 = 1.44; t.05, df = 6 = 1.94 t.10,12 = 1.36; t.05,12 = 1.78 Decision: (either Fail to Reject HO or Reject HO) I recommend copying and pasting one of the above into the answers spot. Here are some test statistics to pick from:(sty ) 2 + ny-1 (n,-1 )s;+(ny -1)sy Sp ; df = no + ny - 2 Sp d df = n - 1
