Suppose that you are testing the hypotheses Ho: p =0.25 vs. HA: p #0.25. A sample of size 350 results in a sample proportion of 0.32. a) Construct a 95% confidence interval for p. b) Based on the confidence interval, can you reject Ho at a = 0.05? 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? a) The 95% confidence interval for p is ().
