Apolitician wants to estimate the proportion of constituents favoring a controversial piece of proposed legislation. suppose that a 99% confidence interval that extends at most 0.05 on each side of the sample proportion is required. how many sample observation are needed?

We are given:

Confidence level = 99%. Therefore, the critical value at 0.01 significance level using the standard normal table is given below:

Margin of error is given in the question as:

Since the previous proportion is not given, therefore, we need to assume

Therefore, the sample size is:

Therefore, 664 sample observations are required.    

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:
