Step-by-step explanation:

(a)

It is provided that in a recent poll, 762 readers responded to the following question:

"If a constitutional amendment to ban a state income tax is placed on the ballot in Tennessee, would you want it to pass?"

The possible responses were Yes, No, or Not Sure.

So, the sample size for this poll is, n = 762.

(b)

The outcomes of the poll are:

1: Yes

2: No

3: Not Sure

The data is categorical.

Categorical data can take labels such as, Gender (M/F), indicators (0/1) and so on.
