A poll conducted in 2018 found that in a random sample of 191
Michiganders, 134 would rate the conditions of Michigan’s roads as
fair or poor.1. Provide a point estimate for
the true proportion of Michiganders that consider the conditions of
Michigan’s roads as fair or poor. Round your answer to 4 decimal
places.
𝑝̂=p^=
2. Construct a 99% confidence interval for
the true proportion of Michiganders that consider the conditions of
Michigan’s roads as fair or poor. Round your answers to 4 decimal
places.
( , )
3. Using the information from 2018 poll as
a planning value, calculate how many Michiganders should be
surveyed to estimate the proportion who consider the conditions of
Michigan’s roads as fair or poor with 99% confidence and a margin
of error of no more than 2.9%.Important: Round
your 𝑧∗z∗ value to exactly three decimal places when
calculating your answer.
