Using the z-distribution, it is found that the smallest sample size required to obtain the desired margin of error is of 4330.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which:

  • \pi is the sample proportion.
  • z is the critical value.
  • n is the sample size.

The margin of error is given by:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

In this problem:

  • The estimate of the proportion is of \pi = 0.8.
  • The desired margin of error is of M = 0.01.
  • 90% confidence level, hence\alpha = 0.9, z is the value of Z that has a p-value of \frac{1+0.9}{2} = 0.95, so z = 1.645.

Then, we solve for n to find the minimum sample size.

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.01 = 1.645\sqrt{\frac{0.8(0.2)}{n}}

0.01\sqrt{n} = 1.645\sqrt{0.8(0.2)}

\sqrt{n} = \frac{1.645\sqrt{0.8(0.2)}}{0.01}

(\sqrt{n})^2 = \left(\frac{1.645\sqrt{0.8(0.2)}}{0.01}\right)^2

n = 4329.6

Rounding up, the smallest sample size required to obtain the desired margin of error is of 4330.
