Assume that a sample is used to estimate a population mean mu. Use the given confidence level and sample data to find the margin of error. Assume that the sample is a simple random sample and the population has a normal distribution. Round your answer to one more decimal place than the sample standard deviation. 95% confidence; n = 21; x-bar = 0.16; s = 0.16

Assume that a sample is used to estimate a population proportion p. Find the margin of error E that corresponds to the given statistics and confidence level. Round the margin of error to four decimal places. In a random sample of 192 college students, 129 had part-time jobs. Find the margin of error for the 95% confidence interval used to estimate the population proportion. 0.0664 0.00225 0.116 0.0598

Conduct the appropriate test. A simple random sample of size $n=15$ is drawn from a population that is normally distributed. The sample mean is found to be $23.8,$ and the sample standard deviation is found to be $6.3 .$ Test whether the population mean is different from 25 at the $\alpha=0.01$ level of significance.
