Homework Answers
a.) b1 = 0.7179
When x1 increases by 1 unit, on average estimated y increases by 0.7179 units.
b2 = 0.7718
When x2 increases by 1 unit, on an average estimated y increases by 0.7718 units.
b.) y = 32.3322+ 0.7179(180) + 0.7718(310)
= 32.3322 + 129.222 + 239.258
= 400.8122
y will be 400.812 when x1 = 180 and x2 = 310
