Question:

Table 9.10 below shows the estimated regression coefficients from the multiple linear regression model to predict post‐rehabilitation distance walked, in metres, on an endurance shuttle walk test from sex, age and pre‐rehabilitation distance walked in 100 COPD patients.

Y or dependent variable: Post‐rehabilitation distance walked (metres)

R 2 = 0.20, residual SD = 349.2 Which variables are statistically significantly associated with post‐rehabilitation distance walked?
