Multiple Choice

Below are the productivity, dexterity, and job satisfaction ratings of ten randomly selected employees.
$\begin{array}{l|l|l|l|l|l|l|l|l|l}\text {Productivity }&23 & 25 & 28 & 21 & 21 & 25 & 26 & 30 & 34 & 36 \\\hline \text { Dexterity }&49 & 53 & 59 & 42 & 47 & 53 & 55 & 63 & 67 & 75 \\\text { Job satisfaction}&56 & 58 & 60 & 50 & 54 & 61 & 59 & 63 & 67 & 69\end{array}$
Find the multiple regression equation that expresses the job satisfaction scores in terms of the productivity and d scores.

• A) \(\hat { S } = 28.28 + 0.0860 \mathrm { P } + 0.517 \mathrm { D }\)
• B) \(\hat { S } = 28.28 + 0.237 \mathrm { P } + 0.728 \mathrm { D }\)
• C) \(\hat { S } = 28.28 + 0.011 \mathrm { P } + 0.437 \mathrm { D }\)
• D) \(\hat { S } = 28.28 + 0.517 \mathrm { P } + 0.0860 \mathrm { D }\)
