The use of electrical stimulation (ES) to increasemuscular strength is discussed in the Journal ofOrthopedic and Sports Physical Therapy. Seventeenhealthy volunteers participated in the experiment.Muscular strength, Y, was measured as a torquein foot-pounds, and ES, X, was measured in mA(microamps). The equation for the line of best fit isgiven as Y = 1.8X + 28.7, and the Pearson correlationcoefficient was 0.61.a. Was the correlation coefficient significantlydifferent from zero? Use α = 0.05.b. Predict the torque for a current equal to 50 mA.HTML Editor
