Data Was Collected from CEOs of Companies Within Both the Low-Tech

question 7

Multiple Choice

Data was collected from CEOs of companies within both the low-tech industry and the consumer products industry. The following printout compares the mean return-to-pay ratios between CEOs in the low-tech industry with CEOs in the consumer products industry. HYPOTHESIS: MEAN X = MEAN Y SAMPLES SELECTED FROM RETURN
$\begin{array} { l l l } \text { industry } 1 & \text { (low tech) } & \text { (NUMBER } = 15 \text { ) } \\ \text { industry } 3 & \text { (consumer products) } & \text { (NUMBER } = 15 \text { ) } \end{array}$
$$\begin{array} { l } X = \text { industry1 } \\Y = \text { industry } 3\end{array}$$
$$\begin{array}{l}\text { SAMPLE MEAN OF X \( =157.286 \) }\\\text { SAMPLE VARIANCE OF \( X=1563.45 \) }\\\text { SAMPLE SIZE OF X \( =14 \) }\\\text { SAMPLE MEAN OF \( Y=217.583 \) }\\\text { SAMPLE VARIANCE OF \( Y=1601.54 \) }\\\text { SAMPLE SIZE OF Y \( =12 \) }\\\\\text { MEAN X - MEAN } Y=-60.2976 \\t=-4.23468 \\\mathrm{P}-\mathrm{VALUE}=\quad 0.000290753 \\\text { P-VALUE } / 2=0.000145377 \\\text { SD. } \mathrm{ERROR}=14.239 \\\end{array}$$ Using the printout, which of the following assumptions is not necessary for the test to be valid?

• A) The population means are equal.
• B) Both populations have approximately normal distributions.
• C) The population variances are equal.
• D) The samples were randomly and independently selected.
