In a random sample of 392 people that were tested for the Norcovirus, it was found that 314 did not have the virus. A 97% confidence interval was constructed to estimate the proportion of the population that does not have the Norcovirus. This confidence interval came out to be (0.76,0.84).
A simple random sample of size n=24 is drawn from a population that is normal distributed. The sample mean is found to be x bar= 66 and the sample standard deviation is found to be s= 16.construct a 98% confidence interval about the population mean. (Round to two decimals)
We surveyed a random sample of 15 domestic violence victims in Columbus, GA, who used the 911. From this sample, 911 response time from calling to police arrival was 8.5 minutes on average with a standard deviation of 2.7 minutes. From the estimation of the population mean (µ) of the arrival time with a 99% confidence interval, what is the upper limit? (Round off to two decimal places if necessary).

A Gallup Poll in December 2019 reported that 46% of the 5120 adults aged 18 and older in the sample said both their mental and their physical health was good or excellent. Gallup announced, "For results based on the combined sample of 5120 adults, aged 18 and older ... the margin of sampling error is 2 percentage points at the 95% confidence level." Confidence intervals for a percentage follow the form estimate±margin of error Based on the information from Gallup, what is the 95% confidence interval for the percentage of all adults aged 18 and older who would say both their mental and physical health was good or excellent? Give your answer as an interval in the form (lower bound, upper bound). Give your numbers as percentages and as whole numbers. confidence interval: $$ What does it mean to have 95% confidence in this interval? A confidence of 95% in the interval means that 95% of all samples of the same size give an interval that contains the actual…
True or False? A researcher wants to be sure the mean difference in the change in blood pressure has a margin of error no more than 5 points and the difference in the standard deviation between the mean blood pressure points from the first medication used to treat high blood pressure and the second medication used to treat high blood pressure is 14 points. The desired sample size required to ensure a 95% confidence interval for the proposed study used to compare the efficacy of two medications used to treat high blood pressure during a cross-over trial is n = 31.
