Question

  1. the table shows the hours, x, spent studying for a test and the test score, y. what is the meaning of the y - intercept if b = 58? type a response

Explanation:

Step1: Recall y - intercept concept

In a linear regression model $y = mx + b$, the y - intercept ($b$) is the value of $y$ when $x = 0$.
In the context of studying hours ($x$) and test score ($y$), when the number of hours spent studying is 0, the test - score is 58. It represents the baseline or starting test score a student would get without any studying.

Answer:

The y - intercept of 58 means that a student who spends 0 hours studying is expected to get a test score of 58.
