An independent mail delivery service wants to study factors that affect the daily gas usage of its delivery trucks. Using data collected from different trucks onvarious days, a company analyst uses software to fit a regression model of the following form.y = 13 +8x, -1.1x, + 2x3 +0.04.x,In this model are the following variables.y= volume of gasoline used (in gallons)X1weight of truck (in tons)x, = tire pressure (in psi, pounds per square inch)weight of initial pačkage load (in hundreds of pounds)X4total distance driven while delivering packages (in miles)Answer the questions below for the interpretation of the coefficient of x, in this model.(a) Holding the other variables fixed, what is the average change in daily fuel used foreach additional ton that a truck weighs?gallon(s)(b) Is this change an increase or a decrease?O increaseO decreaseActivate Windo

There are 1 dependent variable and 4 independent variables. This is multiple regression model. We…
