I am unsure of the formula to use here?
Use the normal distribution to find a confidence interval for a
proportion p given the relevant sample results. Give the best point estimate for p, the margin of error, and the confidence interval. Assume the results come from a random sample.
A 95% confidence interval for p given that p^=0.39
Round your answer for the best point estimate to two decimal places, and your answers for the margin of error and the confidence interval to three decimal places.
Best point estimate =
Enter your answer; Point estimate
Margin of error
Enter your answer; Margin of error
The 95% confidence interval is
Enter your answer; The 95%confidence interval, value 1
Enter your answer; The 95%confidence interval, value 2
Best point estimate =sample proportion = 0.39 We need a 95% confidence interval so Z... View the full answer
