2 The number of emergency calls received by a fire station may be modelled by a Poisson distribution.
During a given period of 13 weeks, the station received a total of 108 emergency calls.
- Construct an approximate \(98 \%\) confidence interval for the average weekly number of emergency calls received by the station.
- Hence comment on the station officer's claim that the station receives an average of one emergency call per day.
