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.

P(X > 45000)

\[ \text{P}(Z > \frac{45000 - 35441}{5108}) \]

\[ \text{P}(Z > 1.8743) \]

\[ 1 - \Phi(1.8743) \]

\[ 1 - 0.9696 = 0.0304 \]

B). For a sample of 75 teachers, what is the probability that the sample mean is greater than $38,000? (In order to receive full credit, be sure you draw a picture, identify your variables, show any formulas and work and label your answer correctly.)

[There is a partial graph drawn above the text, depicting a normal distribution curve. A vertical line at a certain point on the x-axis is marked as 45000, and the area to the right of this point is shaded, indicating the probability being calculated.]
