Suppose that you are testing the hypotheses Ho: p=0.25 vs. HA: p#0.25. A sample of size 200 results in a sample proportion of 0.32. a) Construct a 99% confidence interval for p. b) Based on the confidence interval, can you reject Ho at a = 0.01? 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 99% confidence interval for p is ( ). (Round to three decimal places as needed.)

Suppose the heights of a simple random sample of 100 male sophomores were measured rather than 400. Which of the following statements is true? A) The margin of error for the 95% confidence interval would increase. B) The margin of error for the 95% confidence interval would decrease. C) The margin of error for the 95% confidence interval would stay the same because the level of confidence has not changed. D) The standard deviation owould decrease.
