Let Y be a student's score in points out of 100 possible on an introductory physics final exam. Let X be the number of minutes a student was allowed to spend on the exam. The physics professor randomly assigned X=90 or X=120 to see the effect on score. The estimated regression has intercept 49 pts and slope 0.24pts/min. If students are instead given 5 hours for the test, we'd expect:

100 marks

Step-by-step explanation:

is the number of minutes a student was allowed to spend on the exam

is the students score out of 100

The slope of the regression line is

The intercept is

The equation of the regression line is

If

We would expect a score of 100 as the test has a total score of 100 marks.

answer: 4 (:

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
