Suppose that 35% of all voters voted for a recall. Find the mean of the sampling distribution of the proportion of the 3150 people sampled in an exit poll who voted for the recall.

0.35 is the mean of the sampling distribution of the proportion.

Step-by-step explanation:

We are given the following in the question:

Percentage of voters who voted for recall = 35%

Sample size, n = 3150

We have to find the mean of the sampling distribution.

Formula for mean of sampling distribution:

Putting values, we get,

Thus, 0.35 is the mean of the sampling distribution of people sampled in an exit poll who voted for the recall.

If we are working in a coordinate plane where the endpoints has the coordinates (x1,y1) and (x2,y2) then the midpoint coordinates is found by using the following formula:

midpoint=(x1+x22,y1+y22)

I hope this helps
