Question

The original five points in exercise 13 produce a regression line:

a) With a negative slope
b) With a positive slope
c) Parallel to the x-axis
d) Parallel to the y-axis

Answer 1

The original five points in exercise 13 produce a regression line with a positive slope.

Step-by-step explanation:

The original five points in exercise 13 produce a regression line with a positive slope (b).

A regression line represents the relationship between two variables. In this case, the slope of the regression line indicates the direction and magnitude of the relationship. A positive slope means that as the x-values increase, the y-values also increase.

For example, if we have a set of data points (1, 2), (2, 4), (3, 6), (4, 8), and (5, 10), the regression line would have a positive slope because as the x-values increase, the corresponding y-values also increase.
