The results of a survey show that the percent of adults in a certain town who want to add bike lanes to a major roadway is in the interval (0.47, 0.63) (9 points)

(a) What is the point estimate for the percent who want to add the bike lanes?
(b) What is the poll's margin of error?
(c) If the town's adult population is 75,783, what is the best estimate for the number of people who
would support the bike lanes?

(a) .55

(b) .08

(c) about 42681 people

Step-by-step explanation:

Statistics!!

(a) .55 = point estimate

The point estimate is the middle of those two values, or the average. (.63+.47) / 2 = .55.

(b) .08 = ME

The margin of error is the difference between the point estimate and the outer values of the interval. .63-.55 = .08

(c) 42681 people

We think that .55 of the population want to add the bike lanes, so .55 * 75783 = 41680.65 ≈ 42681
