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.

Nadusha1986 [10]

Answer:

235,000 total overhead

Explanation:

First we calculate the rate for activity

\left[\begin{array}{cccc}&Cost&Pool&Rate\\Setups&60,000&24,000&2.5\\Inspections&120,000&24,000&5\\Assembly&280,000&28,000&10\\\end{array}\right]

Next, we apply this rate to desk lamp

\left[\begin{array}{cccc}&Rate&Desk&Overhead\\Setups&2.5&16,000&40,000\\Inspections&5&15,000&75,000\\Assembly&10&12,000&120,000\\\end{array}\right]

Total Overhead will be the sum of each activity overhead

40,000.00 + 75,000.00 + 120,000.00 = 235,000 total overhead
