ŷ = 3413 + 872 D(admin) + 917 D(cleric) + 1542 D(IT) + 90 D(man)

Interpretation of intercept

if the all independent variables is zero the the values of sales is 3413

Interpretation of slope

.if the value of Administrationis inceased by one unit and all othe independent ariables is constant yhe the sales is increased by 872

if the value of Clericalinceased by one unit and all othe independent ariables is constant yhe the sales is increased by 917

if the value of Manufacturing inceased by one unit and all othe independent ariables is constant yhe the sales is increased by 1542

if the value of IT inceased by one unit and all othe independent ariables is constant yhe the sales is increased by 90
