Question 7. What is the standard error of the proportion given p = 0.34 and n = 50? Question 8. Construct a 90% confidence interval for the population proportion given the following: sample proportion = 0.60 and sample size = 40. Question 9. What minimum sample size is needed to estimate the population mean to within 6 units with 99% confidence given the population standard deviation = 20?
