What is the correlation coefficient of the relationship between the average weekly hours spent studying and the score on the fin
al exam?
0.5049 is the Multiple R value. Remember that for single variable linear regression, Multiple R, which is the square root of R2, is equal to the absolute value of the correlation coefficient. The regression coefficient for Average Weekly Hours Studying (0.03, as shown in the bottom table of the output) is positive, so the slope is of the regression line is positive. Therefore, the correlation coefficient must also be positive.

hello some parts of the question is missing attached below is the missing part
answer : Multiple R = 0.5049 (correlation coefficient )
Explanation:
The correlation coefficient of the relationship between the average weekly hours spent studying and the score on the final exam can be determined/calculated via the relationship between the average weekly hours spent studying and the score of the final exam.
To find the correlation coefficient we will find the square root of R squared

Answer:
$153.01
Explanation:
For computing the monthly payment we need to apply the PMT formula i.e to be shown in the attachment
Given that,
Present value = $8,100
Future value or Face value = $0
RATE = 60 months = 5 years × 12 months
NPER = 5.04% ÷ 12 months = 0.42%
The formula is shown below:
= PMT(RATE;NPER;-PV;FV;type)
The present value come in negative
So, after applying the above formula, the monthly payment is $153.01
