Construct a confidence interval for p1-p2
WebTo construct a confidence interval for the difference in death ratios, we can use the formula: (p1 - p2) ± z*SE where z is the critical value for the desired level of confidence, SE is the standard error of the difference in proportions, and p1 and p2 are the sample proportions. Using a 99% confidence level, the critical value is z = 2.58. WebConstruct a confidence interval for p1−p2 at the given level of confidence. x1=25,n1=242,x2=30,n2=314,90% confidence The researchers are % confident the difference between the two population proportions, p1−p2, is between (Use ascending order. Type an integer or decimal rounded to three decimal places as needed.)
