Hamilton Shelby Sample Size 146 253 Number of low-birth-weight bables 17 32 () Develop a 95% confidence interval estimate for the difference between the prop portions of low-birth-weight babies in the two counties. (Use Hamilton - Shelby. Round your answers to four decimal places.) to (b) Is there conclusive evidence that one of the p significantly more than the other? If yes, which county? Explain, using the results of part (a). Do not perform any test. Because the range of the interv it Shelby county has a significantly higher Incidence. ificantly different (at 95% confidence) from the other. Because the 95% conf are significantly different. Because the rate In Shelby cou conclude that they are indeed different
