Animal Bites of Postal Workers In Cleveland, a sample of 71 mail carriers showed that 8 had been bitten by an animal during one week. In Philadelphia, in a sample of 54 mail carriers, 13 had received animal bites. Is there a significant difference in the proportions? Use a= .01 and use p1 for the proportion of mail carriers in Cleveland. Find the 99% confidence interval for the difference of the two proportions and round all intermediate calculations to at least three decimal places. State the hypotheses and identify the claim H0: H1: one tailed or two tailed Find the critical value(s). Round the answer to at least three decimal places and ensure your degrees of freedom are correct before proceeding. If there is more than one critical value, seperate them with commas. Critical value(s)= Compute the test value. Round the answerto at least two decimal places. z= Reject or do not reject the null hypothesis Is there enough evidence to support the claim Find the 99% confidence interval for the difference of the two proportions. Round the intermediate calculation and final answers to at least three decimal places ( ) < p1-p2 < (

Find the critical value(s). Round the answer to at least three decimal places and ensure your degrees of freedom are correct before proceeding. If there is more than one critical value, seperate them with commas.
Critical value(s)=
Compute the test value. Round the answerto at least two decimal places.
z=
Reject or do not reject the null hypothesis
