Acoach is assessing the correlation between the number of hours spent practicing and the average number of points scored in a game. the table below shows the data:

number of hours spent practicing
(x) 0 0.5 1 1.5 2 2.5 3 3.5 4
score in the game
(y) 5 8 11 14 17 20 23 26 29

part a: is there any correlation between the number of hours spent practicing and the score in the game? 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)

stops on an even number.

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
