We are interested in whether the proportions of female suicide victims for ages 15 to 24 are the same between the white and the black races in the United States. We randomly pick one year to compare the races. The number of suicides estimated in the United States in that year for white females is 4,930. Five hundred eighty were aged 15 to 24. The estlmate for black females is 330. Forty-one were aged 15 to 24. We will let female sulclde vlctlms be our population. (Use a = 0.05.) NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must rst prove that assumption, though.) State the distribution to use for the test. (Round your answers to four decimal places.) ~- (x .x )
