If X overbar=65, S=14, and n=49, and assuming that the population is normally distributed, construct a 99% confidence interval estimate of the population mean, μ.
Assume that you have a sample of n 1 equals 9, with the sample mean Upper X overbar 1 equals 43, and a sample standard deviation of Upper S 1 equals 6, and you have an independent sample of n 2 equals 12 from another population with a sample mean of Upper X overbar 2 equals 35, and the sample standard deviation Upper S 2 equals 7. Construct a 95% confidence interval estimate of the population mean difference between mu...
Here are summary statistics for randomly selected weights of newborn girls: n equals 206 ,x overbar equals29.6hg, s equals7.5hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 27.8 hg less than muless than 30.8hg with only 14 sample values, x overbar equals29.3 hg, and s equals 3.2hg?
A simple random sample of size n equals = 18 is drawn from a population that is normally distributed. The sample mean is found to be x overbar equals 54 and the sample standard deviation is found to be s equals = 19 Construct a 95% confidence interval about the population mean. The 95% confidence interval is ( _____ , _____ ). (Round to two decimal places as needed.)

Here are summary statistics for randomly selected weights of newborn girls: n=235, x overbar=29.42hg, s=7.37hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 27.2hg<μ<31.0hg with only 16sample values, x overbar=29.1hg, and s equals=2.9hg? What is the confidence level What is the confidence interval for the population mean μ? Are the results between the two confidence intervals very different?
