$\mathit{A}$ tossing a coin

$\mathit{B}$ rolling a six-sided number cube

$\mathit{C}$ spinning a spinner with four equal sections

$\mathit{D}$ rolling a three-sided number cube

Step-by-Step Solution

Answer

To simulate Zack’s correctly answering a question, spinning a spinner with four equal sections is used.

Step 1. Identify sample.

A sample is some portion of a large group. Here, the sample is a one choice.

Step 2. Suggest population.

Population is a larger part, of which sample is some portion. Here, population is four choices.

Step 3. Data collection.

Here, the data are from the choice on the spinner. Therefore, it is an observational study.

To simulate Zack’s correctly answering a question, spinning a spinner with four equal sections is used. Therefore, option C is the required answer.
