Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question

**Transcription:**

Fourteen jurors are randomly selected from a population of 5 million residents. Of these 5 million residents, it is known that 45% are of a minority race. Of the 14 jurors selected, 2 are minorities.

(a) What proportion of the jury described is from a minority race?
(Enter your answer in the provided box and round to two decimal places as needed.)

(b) If 14 jurors are randomly selected from a population where 45% are minorities, what is the probability that 2 or fewer jurors will be minorities?
(Round your answer to four decimal places as needed.)

(c) What might the lawyer of a defendant from this minority race argue?

---

(c) Choose the correct answer below.

- ☐ A. The number of minorities on the jury is impossible, given the composition of the population from which it came.
- ☐ B. The number of minorities on the jury is unusually high, given the composition of the population from which it came.
- ☐ C. The number of minorities on the jury is reasonable, given the composition of the population from which it came.
- ☐ D. The number of minorities on the jury is unusually low, given the composition of the population from which it came.
