A simple random sample of front-seat occupants involved in car crashes is obtained Among 2905 occupants notwearing seat belts, 37 were killed. Among 7830 occupants wearing seat belts, 13 were killed Use a 0.05 significancelevel to test the claim that seat belts are effective in reducing fatalities. Complete parts (a) through (c) below.Because the confidence interval limitsBecause the confidence interval limits includefor those not wearing seat belts.c. What do the results suggest about the effectiveness of seat belts?0, it appears that the two fatality rates arevalues, it appears that the fatality rate isOA. The results suggest that the use of seat belts is associated with the same fatality rates as not using seatbelts.B. The results suggest that the use of seat belts is associated with lower fatality rates than not using seat belts.C. The results suggest that the use of seat belts is associated with higher fatality rates than not using seat belts.OD. The results are inconclusive.

Given x1=37, n1=2905, not wearing seat belt x2=13,n2=7830, wearing seat belt

Answered: wearing seat belts, 37 were killed.…

We have developed a new drug used to reduce fever and want to test its efficacy. Ten ER patients who are running a fever agree to take the new drug instead of the traditional treatment. Their temperatures are taken before the drug is administered and 30 minutes after taking the drug. The results are recorded in the Excel file below. Use the data to construct and interpret a 99% confidence interval for the mean change in temperatures of patients after taking this drug using Excel. Be sure to include any explanation necessary along with a sentence that explains what the interval means. First Temp Second Temp 100.1 98.9 101.3 99.1 102.1 99.2 102.7 99 101.9 98.7 100.8 98.6 103.1 99.4 102.5 99.2 103.5 100.1 101.7 99.2

A survey by the society of Human Resource Management asked 350 job seekers why employees change jobs so frequently. The answer selected most (126 times) was "higher compensation elsewhere" as the reason for changing jobs. Then the 95% confidence interval estimate for the population proportion of job seekers who would select "higher compensation elsewhere" as the reason for changing jobs is approximately.

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.
Researchers are studying whether the proportion of homeschooled children in district 1 (considered 1) is less than the proportion of homeschooled children in neighboring district 2 (considered as 2). To test the theory info was gathered: district 1 had 600 students of which 90 were homeschooled. District 2 had 550 students of which 99 were homeschooled. What is the 95% confidence interval for the difference proportion between district 1 and 2? A. (-0.086, 0.026) B. (0.143, 0.217) C. (0.113, 0.187)

Assume that you are interested in examining the home owners in west part of the Ankara. In a random sample of 288 İncek residents, 272 indicated that they were home owners. In another random sample of 600 Çayyolu residents, 390 were home owners.(use 2 digits after decimal point) 92% Confidence interval for the difference between two population proportions is We could state that proportion of home owners in İncek is proportion of home owners in Çayyolu with 92% confidence.
