The Pew Reseаrch Grоup cоnducted а pоll in which they аsked, “Are you in favor of, or opposed to, executing persons as a general policy when the crime was committed while under the age of 18?” Of the 580 Catholics surveyed, 180 indicated they favored capital punishment; of 600 nonreligious (those who don’t associate with a religion) surveyed, 238 favored capital punishment. Is there a significant difference in the proportion of individuals in these groups in favor of capital punishment for persons under the age of 18? Use a level of significance of 0.01. What is the conclusion for this hypothesis test?
