In: Statistics and Probability
You desire to estimate p for a binomial process. You know that p is less than 0.65 and greater than 0.45. Find n, the sample size required, to yield 95% confidence of estimating the true proportion, p, within .02.
Please show all work!
Given that p is less than 0.65 and greater than 0.45. hence the sample proportion
and E=0.02 also the Z value at 95% confidence level is 1.96 which is computed using Z table shown below
So, minimum sample is calculated as
