The weekly excess death rate for each city is the sample mean of the data from several reporting stations (hospitals, clinics, etc.) within a 50 mile radius of the city. Determine the 95% CI for the mean week 7 excess death rate in the city with the highest reported week 7 excess death rate. Assume this city receives data from n= 38 reporting stations and that the sample standard deviation s = 463.

Are the New York City and Pittsburgh mean week 7 excess death rates significantly different? Perform a 2-tail hypothesis test for mu(NYC)- mu(PITT). Assume n(NYC) = 50, n(Pitt) = 35, s(NYC) = 239, s(Pitt) = 214. DO NOT use the approximation minimum(n1-1, n2-1) for the degrees of freedom.
