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 sample data yield r = 0.986 and y = 56.3. What is the best predicted productivity score for a person whose dexterity score is 39? 799.9 80 O - 79.99 79.99

Answer 1

The regression equation is

$\hat{y}=5.50 + 1.91x$

where

x is the dexterity score

and y is the productivity score

Given dexterity score

x = 39

To find the productivity score

$\newline \hat{y}=5.50 + 1.91(39) \newline \hspace*{0.4cm}=79.99$

Productivity score = 79.99

Answer : (Option 4)

          $\mathbf{\circ\ \ 79.99}$
