Answer:

We have the following details:

Confidence level = 99%. Hence, the critical value at a 0.01 significance level is provided below:

$z_{\frac{0.01}{2}}=2.576$

The margin of error is mentioned in the question as:

$E=0.05$

Since we lack information about the previous proportion, we need to assume $\hat{p} = 0.5$ .

Therefore, the required sample size is:

$n=\hat{p}(1-\hat{p}) \left( \frac{z_{\frac{0.01}{2}} }{E} \right)$

$=0.5(1-0.5) \left( \frac{2.576}{0.05} \right)$

$=0.25 \times 51.52^2$

$=663.6 \approx 664$

Thus, it requires 664 sample observations.
