Suppose a sample of 80 with a sample proportion of 0.58 is taken from a population. Which of the following is the approximate 99.7% confidence
interval for the population parameter?

99.7% confidence interval is

Step-by-step explanation:

The formula for a confidence interval for a population proportion is where is the sample proportion, is the sample size, and is the critical score for the desired confidence level.

We are given a sample size of and a sample proportion of . Our critical score for a 99.7% confidence level would be

Therefore, the approximate 99.7% confidence interval for the population parameter is

So we are 99.7% confident that the true population proportion is contained within the interval

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the answer is simply just 6n add the two together as they have an n
