Assume that the following samples are independent. In a random sample of 400 women, 47% favored health care reform. In a random sample of 300 men, 36% favored health care reform. Construct a 98% confidence interval for the difference between the population proportions p1 − p2 . Based on your interval, is there a significant difference between men and women’s opinions on health care reform? Explain. Calculator function:
Determine the point estimate of the population mean and margin of error for the confidence interval. Lower bound is 21, upper bound is 29. The point estimate of the population mean is nothing.
Which one of the following statements about confidence intervals is false? Given the same sample of data, a 99% confidence interval will be wider than a 95% confidence interval. The size of the population affects the width of a confidence interval. The sample statistic determines the center of the confidence interval. The value of z* affects the width of a confidence interval. The general format of a confidence interval is “sample statistic ± margin of error.”
