Assume that the population standard deviation is known and decide whether use of the z-interval procedure to obtain a confidence interval for the population mean is reasonable. Explain your answers. The sample data contain no outliers, the variable under consideration is roughly normally distributed, and the sample size is 20.
To calculate 95% confidence interval we must multiply the standard error by 3, then add and subtract the result to the best estimate. add and subtract the standard error to the best estimate. multiply the standard error in y-intercept by 2, then add and subtract the result to the slope of the graph. multiply the standard error by 2, then add and subtract the result to the best estimate.
among various ethnic groups, the standard deviation of heights is known to be approximately three inches. We wish to construct a 95% confidence interval for the mean height of males from a certain country. Forty eight males are surveyed from a particular country.. The sample mean is 70 inches. The sample standard deviation is 2.6 inches. construct a 95% confidence interval for the population mean height of males of theis country?
Suppose a 90 percent confidence interval to estimate a population proportion was calculated from a sample proportion of 18 percent and a margin of error of 4 percent. What is the width of the confidence interval?
A research doctor wanted to estimate the average total cholesterol level of general adult population. He took a random sample of 12 adults for blood test and obtained the following sample. Assume that total cholesterol level of adult population is normally distributed. Use these data to create a 95% confidence interval for the population mean total cholesterol level. 175, 234, 189, 256, 170, 187, 192, 225, 245, 251, 195, 230 a) Find the sample mean and the standard deviation (round to two decimal places) b) 95% confidence interval for the population mean total cholesterol level (round to two decimal places)

14.) A researcher would like to estimate the mean weight of all adult female American alligators in the Everglades. The mean weight of a random sample of 146 adult female American alligators from the Everglades was found to be 217 pounds. The standard deviation of the weights of all adult female American alligators in the Everglades is known to be 16 pounds.Using a 96% confidence level, determine the margin of error, EE, and a confidence interval for the mean weight of all adult female American alligators in the Everglades. Report the confidence interval using interval notation. Round solutions to two decimal places, if necessary.The margin of error is given by E= ___A 96% confidence interval is given by ___
