A sample of size 350 results in a sample proportion of 0.35. a) Construct a 99% confidence interval for p. b) Based on the confidence interval, can you reject H0 at =0.005 ? Explain. c) What is the difference between the standard error and standard deviation of the sample proportion? d) Which is used in computing the confidence interval
