11.4 Hypothesis Tests about the Slope β1

Is age a predictor of male waist sizes? As men age their metabolism slows, so it makes sense that as men age there waist lines expand. Use the data below and a 1% significance level to test for a positive linear relationship between age and waist circumference (in cm).
Age      58    22     32    31   28     46    41      56     20      54  17      73      52    25
Waist 90.6 78.1 96.5 87.7 87.1 92.4 78.8 103.3 89.1 82.5 86.7 103.3 91.8 75.6
