Four hundred registered votes were randomly selected asked whether gum laws should be changed. three hundred said yes and one hundred said no. the point estimate of the proportion in the population who will respond yes is

The point estimate of the proportion in the population who will respond yes is 0.75.

Solution:

Given, Four hundred registered votes from population were randomly selected and asked whether the gum laws should be changed or not.  

Three hundred said yes and one hundred said no in response.  

We have to find the point estimate of the proportion in the population who has respond yes to the poll.

Now, proportion of population responded yes

Hence, the point estimate of the proportion in the population who will respond yes is 0.75.

it has to be a.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
