Question

The regression equation relating dexterity scores (x) and productivity scores (y) for the employees of a company is y = 5.50 + 1.91x. ten pairs of data were used to obtain the equation. the same data yield r = 0.986 and y = 56.3. what is the best predicted productivity score for a person whose dexterity score is 33?

Answer 1

For this case we have the following equation:
y = 5.50 + 1.91x
Where:
x: dexterity scores
y: productivity scores
For x = 33 we have:
y = 5.50 + 1.91 * (33)
y = 68.53
Answer:
The best predicted productivity score for a person whose dexterity score is 33 is:
y = 68.53
