The average teacher's salary in a certain state is $37,764. Assume a normal distribution with σ = $5100. Assume that the sample is taken from a large population and the correction factor can be ignored. What is the probability that a randomly selected teacher's salary is greater than $41,500 P(X>41,500) B) For a sample of 75 teachers, what is the probability that the sample mean is greater than $39,300 P(x̄>39,300)
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.
