The number of emergency calls per day at a hospital over a period of 120 days is shown below.
Use α = .05 and the p-value approach to see if the above data have a Poisson distribution.
Poisson Distribution
A probability distribution that measures the probability of a given number of events happening in a fixed interval of time or space when these events occur with a known constant mean rate and independently of the time since the last event.
P-Value Approach
A method in statistical hypothesis testing that uses the calculated probability to determine the significance of the observed data.
Emergency Calls
Telephone calls made to emergency services in situations of acute need for assistance.
- Select and apply the right statistical analysis for distinct data sets (goodness of fit evaluation, independence testing, and comparison of multiple proportions).
- Familiarize yourself with the notion of p-value during hypothesis testing and its significance in determining the test result.
- Employ the Poisson distribution method on authentic data sets and compute the anticipated frequencies.
