- It is of interest to know if the average time it takes police to reach the scene of an accident differs from that of an ambulance to reach the same accident. Estimate the difference in the times between the police and the ambulance (mean time for police - mean time for ambulance) using a 99% confidence interval. Based on the confidence interval constructed, do the data support the claim that it takes the same amount of time for the police and the ambulance to reach the scene of an accident? Summary data are as follows: sample size sample mean sample variance Police 60 4.2 minutes 0.08 Ambulance 55 4.5 minutes 0.10 Group of answer choices A. 99% C.I. is (-0.445, -0.155). The sample supports that the times differ. B. 99% C.I. is (-1.070, 0.471). The sample does not supports that the times differ. C. 99% C.I. is (-0.445, -0.155). The sample does not support that the times differ. D. 99% C.I. is (-1.070, 0.471). The sample supports that the times differ.Question 5 > Express the confidence interval (20.9 % , 30.5 % ) in the form of p + ME. Check AnswerPlease help. Thanks
