Based on a poll of 100 small business owners, a real estate development group
claims that 67% of small business owners are in favor of the construction of a
shopping mall in the area. a resident crime prevention group claims that the poll is
not valid and that only 33% of small business owners are in favor of the construction
of a shopping mall in the area.
to determine whether this sample supports the population proportion of 0.67, a
simulation of 100 trials is run, each with a sample size of 200 and a point estimate of
0.33. the minimum sample proportion from the simulation was 0.19 and the
maximum sample proportion from the simulation was 0.58.
the margin of error of the population proportion is found using an estimate of the
standard deviation. what is the interval estimate of the true population proportion?
