Two random samples are taken, one from among UVA students and the other from among UNC students. Both groups are asked if academics are their top priority. A summary of the sample sizes and proportions of each group answering yes" are given below:
UVA (Pop. 1): n1 = 89,\(\hat{p}_{1}\) = 0.81
UNC (Pop. 2): n2 = 86,\(\hat{p}_{2}\) = 0.561
Find a 97.3% confidence interval for the difference P1 – P2 of the population proportions.
Confidence interval = _______
