A regression analysis between weight (y in pounds) and height (x in inches) resulted in the following least squares line: = 128 + 6x. This implies that if the height is increased by 1 inch, the weight on average is expected to:

A) increase by 1 pound
B) decrease by 1 pound
C) increase by 6 pounds
D) decrease by 6 pounds
E) increase by 134 pounds

Least Squares Line

A line of best fit determined by minimizing the sum of the squares of the vertical distances of the points from the line.

Weight

A measure of the heaviness of an object; in statistics, it refers to the emphasis or importance assigned to elements of a dataset.

Height

The measurement of an object or point in relation to ground level or a base level, typically considered vertical distance.
