An aged care office has staffing concerns about the number of calls they receive. If the number of calls per 5-minute interval exceeds 2, then a new receptionist should be hired. Over a particular 1-hour time interval, 29 calls were received. Assuming that the calls arrive in a Poisson distribution, conduct a hypothesis test with a 1% significance level to determine whether a new receptionist should hired.
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.
