The problem presents a partial Minitab output for a multiple regression and asks for the estimated regression equation. First, I restate what the table provides: the intercept (Constant) is 145.321 with a standard error of 48.682, and the coefficients for the predictors are X1 = 25.625, X2 = -5.720, and X3 = 0.823, each with their respective standard errors. The standard practice in linear regression is......Login to view full explanation

PlanFinan is a financial planning organisation. The data in PlanFinan1.xlsx was obtained from PlanFinan’s database of a particular group of clients. Use Excel to obtain a multiple linear regression of the variable "Home" (Y) on the variables "Salary" (X1) and “Savings” (X2). We want to test whether there is a significant linear relationship between the value of home and the two independent variables. According to the regression output, what is the p-value for the test?
