Question

A 2-column table with 10 rows. the first column is labeled x with entries 0.5, 1, 1, 1.5, 2, 2, 2.5, 3.5, 3.5, 4. the second column is labeled y with entries 1, 1, 2, 3, 2, 5, 4, 5, 6, 7. a graph shows the horizontal axis numbered 1 to 4 and the vertical axis numbered 1 to 7. a line increases from 0 to 4. the regression calculator shows the relationship between the hours devin spent playing a video game, x, and the levels he achieved, y. which number of hours can be used to make an extrapolation of the level he could achieve? 2 3 4 5

Answer 1

Based on the graph of this regression calculator, the number of hours that can be used to make an extrapolation of the level he could achieve is: A. 2.

What is a regression line?

A regression line can be defined as a statistical line that best describes the behavior of a data set and such, it is a line that best fits a set of data.

How to determine number of hours?

From the graph of this regression calculator, we can deduce that the linear regression is given by this function y ≈ 1.62x + 0.117; r ≈ 0.92.

Thus, the extrapolation would be given by:

0.14999 ≤ x ≤ 4.35.

0.39999 ≤ y ≤ 7.6.

Therefore, two (2) number of hours can be used to make an extrapolation of the level he could achieve.
