In a certain year, there were 80 days with measurable snowfall in Denver, and 63 days with measurable snowfall in Chicago. A meteorologist computes (80 + 1)/(365 + 2) = 0.22, (63 + 1)/(365 + 2) = 0.17, and proposes to compute a 95% confidence interval for the difference between the proportions of snowy days in the two cities as follows: 0.22 0.17 1.96(0.22)(0.78) 367 + (0.17)(0.83) 367 Is this a valid confidence interval? Explain
