In particular, they were wondering if there was a difference in the angular momentum of the knee at a certain time point during the stroke movement on the rowing machine. To test this, they collected the average angular momentum per stroke for 9 novice rowers (individuals who were not considered experts but used the rowing machine regularly in their personal workout sessions) and for 11 expert rowers (individuals who were currently or had been on a rowing team during their undergraduate studies). Running the 2 independent sample t-test as a bivariate regression where the novice rowers were coded as zero and the expert rowers were coded as one, they obtained the following output in R: > summary (lm.out) Call: 1m (formula knee expert) Residuals: 10 Min Median -1.85911 -0.53311 -0.08995 3Q Max 0.45588 2.36489 Coefficients: Estimate Std.
