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.
You are trying to study the level of personal net worth of a low income populaon. In parcular you are interested in find the confidence interval of the mean level of net worth (net worth can be posive or negave and is measured in thousands of dollars). You do not know the distribuon of the level of net worth of the populaon. For your study, you collected a sample from 100 persons asking them their level of net worth. The results were such that the sample meanXˉ = 3 and the sample variance Sn2 = 100 (Assume you choose the persons randomly, they report their true net worth, and the populaon is sufficiently large.) From this data, find the 90% confidence interval of the mean level of net worth.(Do not use t distribuon)

help thank you!! A new method of HIV testing has been proposed based on a new quick detection procedure where saliva is examined. Suppose that the new method tests 176 HIV positive persons and falsely categorizes (i.e., return negative results) 25 of them. Assuming the current best standard of practice for saliva based quick detection HIV tests has a false negative rate of only 10%, determine if the accuracy of the two tests are significantly different at 95% confidence level. Assume that we can use a z-test. Let ?=False negative rate of new test What is the mean and standard deviation of the normal approximation for p-hat under Null hypothesis? answer choices
Modified True or False Large standard errors will lead to large confidence intervals.
