Number of hours of internet browsing
(x) 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5

Part A: Is there any correlation between the average number of hours of internet browsing and average score on the math test for the students of the class? Justify your answer.
Part B: Write a function which best fits the data
Part C: What does the slope and y-intercept of the plot indicate?

Answers

Answer:Part A: Yes, the correlation is that the longer time a student  spends browsing the internet, the worse score the student will receive on the test. Part B: y= - 1/2x + 95Part C:The slope of the line is -1/2, which represents for every additional hour of internet browsing, the student loses 2 points. The y intercept is 95, which represents a max  score of 95. Let me know if this helps!
