question 20

Multiple Choice

Below are the productivity, dexterity, and job satisfaction ratings of ten randomly selected employees. $$\begin{array} { | l | l l l l l l l l l l | } \hline \text { Productivity } ( \boldsymbol { P } ) & 23 & 25 & 28 & 21 & 21 & 25 & 26 & 30 & 34 & 36 \\\hline \text { Dexterity } ( \boldsymbol { D } ) & 43 & 53 & 59 & 42 & 47 & 53 & 55 & 63 & 67 & 75 \\\hline \text { Satisfaction } ( \boldsymbol { S } ) & 56 & 58 & 60 & 50 & 54 & 61 & 59 & 63 & 67 & 69 \\\hline\end{array}$$ Find the multiple regression equation that expresses the job satisfaction scores in terms of the productivity and dexterity scores.

• A) \(\hat { S } = 28.28 + 0.0237 P + 0.728 D\)
• B) \(\hat { S } = 28.28 + 0.011 P + 0.437 D\)
• C) \(\hat { S } = 28.28 + 0.0860 P + 0.517 \mathrm { D }\)
• D) \(\hat { S } = 28.28 + 0.517 P + 0.0860 D\)
