Question

determine whether the following procedure results in a binomial distribution or a distribution that can be treated as binomial (by applying the 5% guideline for cumbersome). if it cannot be treated as binomial, identify at least one requirement that is not satisfied. in a pew research center survey of 20 subjects, the ages of the respondents are recorded. choose the correct answer below. a. it is binomial or can be treated as binomial. b. it is not binomial because the probability of success does not remain the same in all trials. c. it is not binomial because there are more than two possible outcomes and the trials are not independent. d. it is not binomial because there are more than two possible outcomes.

Explanation:

A binomial distribution has two possible outcomes (success or failure). Recording ages has many possible values, not just two. Trials are independent in this survey context but the multiple - outcome nature disqualifies it.

Answer:

D. It is not binomial because there are more than two possible outcomes
