Use Table A to answer the following: P ( − 0.56 ≤ Z ≤ 1.87)
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.
Use Table A to answer the following:
P ( − 0.56 ≤ Z ≤ 1.87)
The value of is,
Use the Table A: Areas of a Standard Normal Distribution: to obtain probability less than 1.87.
- Locate the value 1.8 in column z.
- Locate the value 0.07 in top row.
- The intersecting value of row and column is 0.9693.
Use the Table A: Areas of a Standard Normal Distribution: to obtain probability less than -0.56.
- Locate the value -0.5 in column z.
- Locate the value 0.06 in top row.
- The intersecting value of row and column is 0.2877.
