A group will camp for 10 nights in an area where malaria occurs.
The table gives information about mosquitoes at two possible campsites.
| Campsite | Mean number of mosquito bites per person per night | Mosquitoes carrying the malarial protist (%) |
|---|---|---|
| P | 12 | 0 |
| Q | 5 | 4 |
The organisers have enough insecticide to spray only one campsite. They decide to spray campsite P because people receive more mosquito bites there.
Evaluate this decision.
