A call center agent receives an average of 28 calls per hour. Assuming that this follows a Poisson distribution, use the normal approximation to determine the probability that in an hour, the call center agent will receive: 32 or more calls. greater than 25 calls. exactly 44 calls.
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.
A call center agent receives an average of 28 calls per hour. Assuming that this follows a Poisson distribution, use the normal approximation to determine the probability that in an hour, the call center agent will receive:
- 32 or more calls.
- greater than 25 calls.
- exactly 44 calls.
