Let P₁ Represent the Population Proportion of U

question 90

Short Answer

Let p₁ represent the population proportion of U.S. senatorial and congressional (House of Representatives) Democrats who are in favor of a new modest tax on junk food. Let p₂ represent the population proportion of U.S. senatorial and congressional Republicans who are in favor of a new modest tax on junk food. Out of the 265 Democratic senators and members of Congress, 106 of them are in favor of a junk food tax. Out of the 285 Republican senators and members of Congress, only 57 are in favor of a junk food tax. At α = .01, can we conclude that the proportion of Democrats who favor a junk food tax is more than 5 percent higher than the proportion of Republicans who favor the new tax (using critical value rules)?
