Answer

Answer:

D. About one - fourth of the cable - television customers are not satisfied.

Explanation:

Step1: Calculate proportion of not - satisfied cable customers

The number of not - satisfied cable customers is 285 and the total number of cable customers is 1109. The proportion is $\frac{285}{1109}\approx0.257$.

Step2: Analyze option A

The data is categorical (satisfied or not satisfied), not quantitative, so A is false.

Step3: Analyze option B

The percentage of not - satisfied Internet customers is $\frac{212}{2032}\times100%\approx10.43%$. The percentage of not - satisfied cable customers is $\frac{285}{1109}\times100%\approx25.7%$. So B is false.

Step4: Analyze option C

The number of cable customers is 1109 out of 3141 total customers. $\frac{1109}{3141}\approx0.353$, not about half, so C is false.
