Problem 7.On our final attempt, we divide the neighborhoods into two categories: "mostly white"White50) and "mostly minority" (White < 50). Here is a summary of the data:sd(Schools)Number ofNeighborhoods70Mean(Schools)Group725.53826.06Mostly MinorityMostly White 3454.6068.77A. Using a two-sample t test, test the claim that there is no difference in school performancebetween mostly minority and mostly white neighborhoods. Use a significance level of 1%.B. Name one assumption necessary for the two-sample t test that is violated in this analysis.Justify why the assumption does not hold.
