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:
Is this a valid confidence interval? Explain.
