Assume that from a sample of 100 tires the tire pressure has a 95% confidence interval given by 32 Pounds Per Square (PSI) Inch + 3 PSI. What is the Error Term? What are Upper and Lower values of the confidence interval? What is the Standard Error? What are the Upper and Lower values for a 99% Confidence Interval? Discuss about the probability that another data sample of 100 tires would show a sample mean equal to 38 PSI.

In order to estimate the percentage of adults who file their taxes at least two weeks be deadline, a 99% confidence interval is constructed. The interval ends up being from 0.756 to 0.864. Which of the following could be a 90% confidence interval for the same sample data? I. 0.749 to 0.871 II. 0.776 to 0.844 III. 0.765 to 0.875 IV. 0.799 to 0.841 OI only OIV only None of the answer options are reasonable 90% confidence intervals. III only O II only

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.

Express the confidence interval (84.4 %, 95.2 % ) in the form of p ME.
