is there a significant difference in the proportion

In Cleveland, a random sample of 71 mail carriers showed that 8 had been bitten by an animal during one week. In Philadelphia, in a random sample of 78 mail carriers, 16 had received animal bites. Is there a significant difference in the proportions? Use a = 0.05. O There is not enough evidence to support the claim that there is a difference in the proportions because the test value -1.683 is inside the noncritcal region -1.96
