Question

Cardiorespiratory fitness is widely recognized as a major component of overall physical well-being. Direct measurement of maximal oxygen uptake (VO2max) is the single best measure of such fitness, but direct measurement is time-consuming and expensive. It is therefore desirable to have a prediction equation for VO2max in terms of easily obtained quantities. A sample is taken and variables measured are age (years), time necessary to walk 1 mile (mins), and heart rate at the end of the walk (bpm) in addition to the VO2 max uptake. The equation from a multiple regression is (V02) = 0.097*(age) + 0.038*(HR) + 0.027*(time) + 3.052. If a person is 44.256 years old, has a heart rate of 142.554 bpm, and a walking time of 13.186 minutes, and a maximum oxygen intake of 17.574 L/min, what is the residual? Question 14 options: 1) 4.4561 2) -31.1381 3) -4.4561 4) We do not know the observations in the data set, so we cannot answer that question. 5) -7.5081 Cardiorespiratory fitness is widely recognized as a major component of overall physical well-being.

Explanation / Answer

From the Given Equation the residual = (VO2) - 0.097*(age) - 0.038(HR) - 0.027*(time) - 3.052

Plugging in the given data, we get: 17.574 - 0.097*44.256 - 0.038*142.554 - 0.027*13.186 - 3.052 = 4.4561
