It's been a long time since I've done (least squares?) multiple regression, is the calculation below correct?(adsbygoogle = window.adsbygoogle || []).push({});

y data points

6,054

7,200

6,243

5,536

4,879

y hat = 5,984

x data points

414

351

425

372

328

x hat = 378

Sum of xy's residuals = 39,643

Sum of (x-x hat) squared = 6,770

slope = 5.86

intercept = 5,984 - (5.86*378)

intercept = 3,769

y = 3,769 + (5.86*x)

is that right?

So for an x value of 400, it is

y = 3,769 + (5.86*400)

y = 3,769 + 2,344

y = 6,113

is that right?
