Calculate the margin of error and construct a confidence interval for the population proportion using the normal approximation to the p-distribution (if it is appropriate to do so). Standard Normal Distribution Table a. p = 0.7, n=140, a = 0.05 E Round to four decimal places if necessary Enter 0 if normal approximation cannot be used E <p< Round to four decimal places if necessary Enter 0 if normal approximation cannot be used b. p = 0.3, n = 180, α = 0.05 E = =
E<p< Round to four decimal places if necessary Enter 0 if normal approximation cannot be used
