Given two independent random samples with the following results:
n1=215
x1=17
n2=140
x2=53
Use this data to find the 98% confidence interval for the true difference between the population proportions.
Step 1 of 4: Find the values of the two sample proportions, p^1 and p^2 Round your answers to three decimal places.
Step 2 of 4: Find the critical value that should be used in constructing the confidence interval.
Step 3 of 4: Find the value of the standard error. Round your answer to three decimal places.
Step 4 of 4: Construct the 98% confidence interval. Round your answers to three decimal places.
