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.

Answer:
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 and Explanation:
1. The computation of overhead rate based on direct labor cost is shown below:-
Overhead rate = Overhead applied × 100 ÷ Direct labor cost
= 888 × 100 ÷ 1,200
= 74%
2. The Preparation of job-order cost sheet for the four jobs is shown below:
Particulars Job 86 Job 87 Job 88 Job 89
Beginning balance $6,888 $6,820
Direct materials $3,000 $7,000 $2,100 $1,500
Direct labor $800 $6,000 $900 $500
Applied overhead
is 74% of direct labor $592 $4,440 $666 $370
Total $11,280 $24,260 $3,666 $2,370
3. The computation of ending balances of Work in Process and Finished Goods is shown below:-
Work in process of Job 88 = $3,666
Finished goods = Total of Job 86 + Total of Job 89
= $11,280 + $2,370
= $13,650
4. The computation of the Cost of Goods Sold for March is shown below:-
Cost of goods sold is
= Job 87
= $24,260
