Question

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.

Answer 1

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

Explanation:

We are given the following in the question:

Percentage of voters who voted for recall = 35%

`p = 35\% = 0.35`

Sample size, n = 3150

We have to find the mean of the sampling distribution.

Formula for mean of sampling distribution:

`\mu = p`

Putting values, we get,

`\mu = 0.35`

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