A student is assessing the correlation between the average number of hours of internet browsing and average score on a math test. The table below shows the data: Number of hours of internet browsing (x) 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 Score on math test (y) 95 94 93 92 91 90 89 88 87 86 Part A: Is there any correlation between the average number of hours of internet browsing and average score on the math test? Justify your answer. (4 points) Part B: Write a function which best fits the data. (3 points) Part C: What does the slope and y-intercept of the plot indicate? (3 points)

Part A:

I think there is a correlation because the more hours a student spends browsing the lower his score is. If you calculate the correlation coefficient you would get -0.9963777 meaning there is a strong negative correlation.

Part B:

The function that best represents the data is y=-2.2545x+95

Part C:

The slope is -2.2545 meaning for every unit of x y decreases by -2.2545. The y intercept is 95 meaning when x equal 0 y equals 95.

HOPE THIS HELPS :)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
