We suspect the proportion p. of African-American families earning between $100000 and $149999 a year is less than the the proportion Pw of white families earning between $100000 and $149999 a year. So we take as our null hypothesis that p.=Pw and as our alternative hypothesis Pa<Pw. We decide to test this at level of significance 0.05. We sample 1034 African-American families and find 107 earn between $100000 and $149999 a year. We also sample 1324 white families and find 229 earn between $100000 and $149999 a year. nw = ="d The pooled estimate is p %3D = The critical number is The value of the test statistic (P-Pw)//p*(1-p)*(1/n.+1/n,) is TS = %3D The P-value is P= (Give P to three decimal places, as well as you able)
