Table 2 Bootstrap results for weekends. The table reports the mean values of intercept q and slope m for 500 bootstrap iterations. The bootstrapped 95% Confidence Intervals (CI) and the p-value p for the t-test on the slope m (\(p \leq 0.05\): ∗, \(p \leq 0.01\): ∗∗, \(p \leq 0.001\): ∗∗∗) are also reported
