The heights, in inches, of orangutans are normally distributed with a population standard deviation of 3 inches and an unknown population mean. If a random sample of 17 orangutans is taken and results in a sample mean of 57 inches, find the error bound (EBM) of the confidence interval with a 95% confidence level. z0.10 z0.05 z0.025 z0.01 z0.005 1.282 1.645 1.960 2.326 2.576
Here are summary statistics for randomly selected weights of newborn girls: n=232, x overbar=27.4hg, s=6.1hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence interval 26.3hg<u<28.9hg with only 16 sample values, x overbar= 27.6hg, and s=1.8hg? What is the confidence interval for the population mean u?

Researchers investigating the new Johnson & Johnson COVID Vaccine selected a random sample of 200 individuals and gave them the vaccine. Of those, 52 indicated they were experiencing side effects from the vaccine. If 5,000 people took the drug, which of the following is closest to the interval estimate of the number of people who would indicate they were experiencing side effects from the vaccine at a 95 percent confidence level? a (940, 2750) b (995, 1605) c (0.199, 0.321) d (0.209, 0.311) e (1045, 1555)

Are these results very different from the confidence interval 29.0 hg<μ<32.4 hg with only 18 sample values, x=30.7 hg, and s=3.4hg?
A national opinion poll found that 44% of all American adults agree that parents should be given vouchers that are good for education at any public or private school of their choice. The result was based on a small sample. How large of a sample is required to obtain a margin of error of 0.03 in a 99% confidence interval? a. Use the national opinion poll from a previous study to find the sample size: b. Use the conservative guess of p = 0.5 to calculate the sample size:
A random sample of 240 adults over the age of 40 found that 144 would use an online dating service.
