"According to a 2018 Gallup poll, 5% of U. S. adults consider themselves to be vegetarian. Nonwhite Americans (9%) are three times as likely as white Americans (3%) to describe themselves as vegetarian." This statement is based on a random sample of 1033 American adults interviewed in July 2018, in which 270 respondents identified as "nonwhite" and 742 as "white. The cited value 5% is part of the:

a. Experimental
b. Conditional
c. Observational
d. Anecdotal
e. Marginal

and distribution of the:
a. Ethnicity, given diet choice
b. Diet choice, given ethnicity
c. Ethnicity, D. Diet

(c) Observational Distribution

(d) Diet Choice

Step-by-step explanation:

Out of 1033 American adults interviewed in July 2018, 5% consider themselves to be vegetarian.

Since the poll observes the diet habit of the respondents, the cited 5% is part of the Observational distribution of whether the respondent is a vegetarian or not (which is the Diet Choice).

If on the other hand, the poll seeks to manipulate the conditions of the study, it would have been an experimental distribution.
