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

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
