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. Why did the scientist run the simulations to find additional possible proportions of mosquitoes in the area that carry the disease?

Question 5 (1 point)
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.
Why did the scientist run the simulations to find additional possible
proportions of mosquitoes in the area that carry the disease?
Question 6 (1 point)
A student measures the wingspans of 40 local dragonfly specimens selected at
random. The sample mean is 6.8 centimeters with a margin of error of 0.9
centimeters. Based on this information, what are plausible values for the
mean wingspans of the population of local dragonflies?
