Predict torque for current-pearson correlation coefficient

Reference no: EM13120362

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.
