Assume that 12 jurors are randomly selected from a population in which 82% of the people are Mexican-Americans. Refer to the probability distribution table below and find the indicated probabilities. xx P(x)P(x) 0 0+ 1 0+ 2 0+ 3 0+ 4 0.0002 5 0.0018 6 0.0096 7 0.0373 8 0.1062 9 0.2151 10 0.2939 11 0.2434 12 0.0924 Does 7 Mexican-Americans among 12 jurors suggest that the selection process discriminates against Mexican-Americans? A. no B. yes Is it correct answer B?
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.
Assume that 12 jurors are randomly selected from a population in which 82% of the people are Mexican-Americans. Refer to the
| xx | P(x)P(x) |
|---|---|
| 0 | 0+ |
| 1 | 0+ |
| 2 | 0+ |
| 3 | 0+ |
| 4 | 0.0002 |
| 5 | 0.0018 |
| 6 | 0.0096 |
| 7 | 0.0373 |
| 8 | 0.1062 |
| 9 | 0.2151 |
| 10 | 0.2939 |
| 11 | 0.2434 |
| 12 | 0.0924 |
