Ill medal , and fan .
In a comparison of the number of hours spent studying for a test and a student's grade on the test, the line of best fit was found to be y = 12.5x + 75, with a correlation coefficient of 0.9. Based on this information, what is the meaning of the yintercept of the equation?
Students earn 12.5 additional points on the test for each hour studied.
Students earn 75 additional points on the test for studying at least an hour.
There is no relationship between the two variables, so the yintercept has no meaning.
Students who don't study would expect to score a 75

Best ResponseYou've already chosen the best response.1hints: the y intercept occurs when x = 0 x = number of hours studied y = score on the test

Best ResponseYou've already chosen the best response.1yeah if x = 0 then y = 75 telling us that we predict that those who don't study at all will get a 75
