The alternative hypothesis expressed in words is the proportion of cancer diagnoses attributable to lung cancer is more than 0.32 . The alternative hypothesis is expressed symbolically as Hy:p > 0.32. (Type integers or decimals. Do not round.) The hypothesis test is right-tailed because the alternative hypothesis contains >.
