A startup team is interested in creating a productivity app. Inestimating the cost of creating the app, they collected sample dataand developed the following regression equation:

y? =?8.934+20.726x1+0.356x2+1.901x3

where	x1= number of developers
	x2= number of hours spent creating the app
	x3= cost of software and testing ($'000)
	y= total cost of creating app ($'000)

a. What is the value of b2 inthe equation?

b2=

b. Does it make sense to interpret b0in this equation?

Yes

No

c. Predict the cost of creating an appinvolving 2 developers, 650 hours and $20,000 in software andtesting costs.
