Consider random samples of size 50 from a population with proportion 0.35.

lisov135 [29]

Answer:

The mean is $\mu_{\^ p } = p = 0.35$

The standard error is $SE = 0.06745$

Step-by-step explanation:

From the question we are told that

The sample size is n = 50

The population proportion is $p = 0.35$

Generally given that the sample size is large enough , then the mean of the distribution is mathematically represented as

$\mu_{\^ p } = p = 0.35$

Generally the standard error of the distribution is mathematically represented as

$SE = \sqrt{\frac{p (1- p )}{n} }$

=> $SE = \sqrt{\frac{0.35 (1- 0.35 )}{50} }$

=> $SE = 0.06745$

So 100% is 250 CDs
1% is therefore 2.5 CDs
75 ÷ 2.5 = 30%
100% - 30% = 70% is the answer
