Refer to the sample data given in Exercise 1 and find the multiple regression equation with the response (y) variable of €œinterval-after€ time and predictor (x) variables of duration and €œinterval-before€ time. Identify the value of the multiple coefficient of determination R2, the adjusted R2, and the P-value representing the overall significance of the multiple regression equation. Use a 0.05 significance level and determine whether the regression equation can be used to predict the time interval after an eruption given the duration of the eruption and the time interval before that eruption.
