A scientist is worried about a new disease being spread by mosquitoes in an area. The
scientist captures a random sample of 137 mosquitoes from the area and tests them to find out whether they carry the disease. In this sample, 22 of the mosquitoes were carrying the disease.
Using this information, the scientist uses 100 simulations of additional samples with the
same proportion of disease-carrying mosquitoes from the sample to determine that the
standard deviation for the proportion of mosquitoes carrying the disease is approximately
0.029.
1. Estimate the proportion of mosquitoes in the area that carry the disease, and provide a margin of error. Explain or show your reasoning.
2. Why did the scientist run the simulations to find additional possible proportions of
mosquitoes in the area that carry the disease?
