2. A poll asks a random sample of 500 parents whether they prefer traditional public schools or charter schools for their children. Suppose that 30% of parents in the population prefer charter
schools.
a) What is the mean of the sampling distribution of p, the proportion of adults in the
samples of 500 who prefer charter schools?
b) What is the standard deviation of p?
c) What is the probability that more than 35% of the sample are in favor of charter schools?

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
