A coach is assessing the correlation between the number of hours spent practicing and the average number of points scored in a game. The table shows the data: Number of hours spent practicing (x)00.511.522.533.54 Score in the game (y)5811141720232629 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 that best fits the data. (3 points) Part C: What does the slope and y-intercept of the plot indicate? (3 points)

(A) There is a perfect correlation between the two variables.

(B) The line of best fit is, y = 6 x + 5.

(C) The slope of a regression line represents the average rate of change.

Step-by-step explanation:

(A)

The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

Compute the correlation coefficient between the number of hours spent practicing and the score in the game using the Excel function "CORREL(array1, array2)".

The correlation coefficient between the number of hours spent practicing and the score in the game is 1.00.

This implies that there is a perfect correlation between the two variables.

(B)

Compute the line of best fit as follows:

Consider the points (1.5, 14) and (3.5, 26):

(image is there)

Thus, the line of best fit is, y = 6 x + 5.

(C)

The slope of a regression line represents the average rate of change in y caused by x.

The y-intercept is the value of y for x = 0, i.e. it is the point where the line crosses the x-axis.

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
