Suppose that 35% of all voters voted for a recall. Find the mean of the sampling distribution of the proportion of the 3150 peop

Aloiza [94]

Answer:

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%

$p = 35\% = 0.35$

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.

Solution 1 :-

Given expression ,

$\implies 13^{\frac{3}{4}}$

We know that, $a^{\frac{m}{n}} = \sqrt[n]{a^m}$

Therefore , this can be written as ,

$\implies \sqrt[4]{13^3}$

Solution 2:-

Given expression ,

$\implies \sqrt[3]{24^{10}}$

We know that, $a^{\frac{m}{n}} = \sqrt[n]{a^m}$

Therefore, this can be written as ,

$\implies 24^{\frac{10}{3}}$
