The following data gives the number of hours 10 students spent studying and their corresponding grades on their midterm exams. Hours Spent Studying 0.5 1 2 2.5 3.5 4 4.5 5 5.5 6 Midterm Grades 60 63 69 72 78 81 84 87 90 96 Step 3 of 3 : Calculate the correlation coefficient, r. Round your answer to three decimal places.

The final answer would be the correlation coefficient r =0.9975

Step-by-step explanation:

For this case we have the following data given:

x: 0.5 1 2 2.5 3.5 4 4.5 5 5.5 6

y: 60 63 69 72 78 81 84 87 90 96

And we want to calculate the correlation coefficient, and we have the following formula to do this:

For our case we have this:

n=10  

And replacing we got:

The final answer would be the correlation coefficient r =0.9975

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
