3) A random sample of ?? = 11 in Chicago gave the following information concerning violent crime rates (per million population): ?? = 3.42 and ?? = 0.79. Another random sample of ?? = 14 in Las Vegas gave the following information concerning violent crime rates: ?? = 3.77 and ?? = 0.92. Do the data indicate that violent crime rate in Chicago is higher than that in Las Vegas? Use a 1% level of significance.
