I need correct answer for given question.

The following data is representative of that reported in an article on nitrogen emissions, with X = burner area liberation rate (MBtu/hrftz) and y = NOX emission rate (ppm): X 100 125 125 150 150 200 200 250 250 300 300 350 400 400 y 150 150 170 220 200 330 280 390 440 450 390 590 610 680 IE use SALT (a) Assuming that the simple linear regression model is valid, obtain the least squares estimate of the true regression line. (Round all numerical values to four decimal places.) y = 741.08 + 1.705x V (b) What is the estimate of expected NOX emission rate when burner area liberation rate equals 235? (Round your answer to two decimal places.) 359.59 x ppm (c) Estimate the amount by which you expect NOX emission rate to change when burner area liberation rate is decreased by 60. (Round your answer to two decimal places.) 102.30 X ppm
