x= big price of the contract in millions and y = cost ofoverrun (percent of the bid price).
x = 6, 10, 3, 5, 9, 18, 16, 21
y = 31, 25, 39, 35, 29, 12, 17, 8
Find the slope, b, and the intercept, a, for the least-squaresline Write the equation of the least squares line.
If an overrun contract was bid at 12 million dollars, whatdoes the least squares line predict for the cost of overrun (as apercent of bid price)?

1.  2. By using statitistical soft ware we can easilycalculate
x= big price of the contract in millions and y = cost ofoverrun (percent of the bid price).
x = 6, 10, 3, 5, 9, 18, 16, 21
y = 31, 25, 39, 35, 29, 12, 17, 8
The regression equationis

y = 43.0 - 1.68 x

--------------
substitute X = 12 inthe regression equatin then you will get the overrun cost (AS APERCENT OF BID PRICE )
