Let xbe the elevation (in thousands of feet) for an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation.

Explanation / Answer

Solution:

We are give data of X and Y

We have to find coefficient of X that is b.

We use MINITAB for finding this.

First enter data of X and Y in C1 and C2 cells

Follow the following path in MINITAB:

stat-------->Regression-------->Regression...-------->

Response:Y

Predictors:X

press ok

We get following table:

The regression equation is
Y = - 10.3 + 12.9 X

Predictor Coef SE Coef T P
Constant -10.28 45.53 -0.23 0.836
X 12.913 6.370 2.03 0.136

S = 11.83 R-Sq = 57.8% R-Sq(adj) = 43.7%

Here b = 12.913 is the correct answer.

Option(A) is correct

Done
