Management at a local company asked employees if they were interested in obtaining job training. Responses are summarized by employment type (salaried or hourly), and whether the employee is interested (yes or no) in job training. Salaried Hourly Total yes 68 56 124 no 11 44 55 total 79 100 179 Compute the probability that an employee is salaried. Give your answer as a decimal, precise to at least three decimal places. p salaried = Next, compute the probability that an employee who is interested in training is salaried. Gives your answer as a decimal, precise to at least three decimal places. p salaried /yes= Finally, use the results from the two preceeding calculations to determine whether or not employment type and interest in training are independent. No, the two events are not independent. Yes, the two events are independent.
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.

Next, compute the probability that an employee who is interested in training is salaried. Gives your answer as a decimal, precise to at least three decimal places.
p salaried /yes=
Finally, use the results from the two preceeding calculations to determine whether or not employment type and interest in training are independent.
