A medical school claims that more than 28% of its students plan to go into general practice. It is found that among a random sample of 130 of the school\'s students, 32% of them plan to go into general practice. Test the school\'s claim using alpha = .05. Solution Test statistic is ((hat)- )/(p(1-p)/n) Here (hat)= .32, =.28 and n= 130 So we have (.32-.28)/.28*.72/130= .04/.03938= 1.02 P value (from normal table) is .1539 (so we wouldn\'t find evidence to support the schools claim)..
