Chapter 11, Problem 4PT

To determine

To find: Whether the given experiment is a binomial experiment or can be reduced to binomial experiment and if so describe a trial, determine the random variable and state $n$ , $p$ and $q$ .

Answer to Problem 4PT

The experiment can be reduced to binomial experiment, the failure is no, a trial is asking a teacher, and the random variable is the number of yeses and $n=15$ , $p=0.65$ and $q=0.35$ .

Explanation of Solution

Given:

Consider the given survey.

Calculation:

This experiment can be reduced to a binomial experiment. The success is yes while the failure is no, a trial is asking a teacher, and the random variable is the number of yeses.

The values of $n=15$ , $p=0.65$ and $q=0.35$ .

Therefore, the experiment can be reduced to binomial experiment, the failure is no, a trial is asking a teacher, and the random variable is the number of yeses and $n=15$ , $p=0.65$ and $q=0.35$ .
