Training hours are positively related to muscle percentage: clients tend to gain 0.9 percentage points for each hour they work out per week. The negative B-coefficient for the interaction predictor … WebIf we measured age at a more granular level, then no, the slope wouldn’t change. It might change slightly at a level of rounding, but that’s it. If you changed the unit of measurement to months, however, so that 25 years 6 months = 306 months, then yes the slope would change as the units change. Q14: Two of the males have low scores.

The negative intercept tells you where the linear model predicts revenue (y) would be when subs (x) is 0. Your question appears to be prompted by confusion about the fact that in your fitted model, E ( Y x = 0) ≠ 0, even though logically, you would expect no revenue then.
