The regression model with album sales as dependent variable and advertising budget, number of plays on the radio, and attractiveness of the band as independent variables, was significant, F(3, 196) = 129.50, p < .001.
Advertising budget, b = 0.51, t = 12.26, p < .001, 95% CI [0.07, 0.10],
number of plays on the radio, b = 0.51, t = 12.12, p < .001, 95% CI [2.82, 3.92],
and attractiveness of the band, b* = 0.19, t = 4.55, p < .001, 95% CI [6.28, 15.89] significantly predict album sales.
For all these effects other independent variables are assumed to be held constant.
Together the variables explain 66.5% of the variance in album sales, reflecting a strong prediction (R2 = .67).
