In Exercises, use either the critical-value approach or the P-value approach to perform the required hypothesis test. Ballistic Fingerprinting. Guns make unique markings on bullets they fire and their shell casings. These markings are called ballistic ngerprints. An ABCNEWS Poll examined the opinions of Americans on the enactment of a law “. . . that would require every gun sold in the United States to be test-red first, so law enforcement would have its fingerprint in case it were ever used in a crime.” The following problem is based on the results of that poll. Independent simple random samples were taken of 537 women and 495 men. When asked whether they support a ballistic fingerprinting law, 446 of the women and 307 of the men said “yes.” At the 1% significance level, do the data provide sufficient evidence to conclude that women tend to favor ballistic fingerprinting more than men?
