Part A: Yes, there is a correlation between the number of hours students spent studying and the score on the music test because As we increase the hours of studying by 0.5 hours, then the music score increases by 2.
Part B: A function that best fits the data is; y = 60 + 4x
Part C: The slope and y-intercept of the plot indicates that Y is the score obtained in music test and number of hours spent on studying.
<h3>How to find the correlation of line of best fit?</h3>
We have given the table below showing the data:
Number of hours spent studying (x) 0 0.5 1 1.5 2 2.5 3 3.5 4
Score on music test (y) 60 62 64 66 68 70 72 74 76
A) As we increase the hours of studying by 0.5 hours, then the music score increases by 2.
B) The function which best fits the data for the correlation from the above is; y = 60 + 4x
C) The slope and y-intercept of the plot indicates that Y is the score obtained in music test and number of hours spent on studying.
The slope of the above equation represents the rate of increase in music score with respect to an increase in the number of hours spent on studying.
The y-intercept gives the music score when the number of hours spent on studying is zero.
