Description of least squares

Reference no: EM13112374

In fitting a least squares line to n=15 data points, the following quantities were computed: SSxx=55, SSyy=198, SSxy=-88, x-bar=1.3, and y-bar=35.

Determined the following:

y=B0+B1X

y=37.08-1.6X

SSE=57.2

S squared = 4.4

1. Find 90% confidence interval for B1/Interpret answer

2. Find 90% prediction interval for Y when x=15
