To investigate the dependence of energy expenditure on body build, researchers used underwater weighing techniques to determine the fat-free body mass $x$ (in $\mathrm{Kg}$ ) for each of seven men. They also measured the total 24- hour energy expenditure $y$ (in Kcal) for each man during conditions of quiet sedentary activity. If the sample correlation coefficient $r=0.98$, calculate the value of the test statistic to determine whether or not there is a linear relationship between fat-free mass and energy expenditure. 9.814 11.428 17.234 7.6745
