Find the sample size, n, needed to estimate the percentage of adults who have consulted fortune tellers. Use a 0.02 margin of er

Brrunno [24]

Answer: 2172

Step-by-step explanation:

Formula to find the sample size n , if the prior estimate of the population proportion(p) is known:

$n= p(1-p)(\dfrac{z^*}{E})^2$ , where E= margin of error and z* = Critical z-value.

Let p be the population proportion of adults have consulted fortune tellers.

As per given , we have

p= 0.20

E= 0.02

From z-table , the z-value corresponding to 98% confidence interval = z*=2.33

Then, the required sample size will be :

$n= 0.20(1-0.20)(\dfrac{2.33}{0.02})^2$

$n= 0.20(0.80)(116.5)^2$

$n= 2171.56\approx2172$

Hence, the required sample size = 2172
