A confidence interval for the population mean is: A. a range of values that certainly does not contain the sample mean. B. a range of values which contains the mean of the population with certainty. C. a range of possible values of the sample mean. D. a range of values which will contain the mean of the population with a specified level of confidence.

Suppose a sample is taken and a confidence interval is constructed for the mean of the distribution. Which of the following is always found at the center of the interval? the population mean population mean only if there are not many outliers. Neither the sample mean nor the population mean. With a sample anything can be in the center. The sample mean

Constructing Confidence Intervals Use the data set to (a) find the sample mean, (b) find the sample standard deviation, and (c) construct a $99 \%$ confidence interval for the population mean. Assume the population is normally distributed. If convenient, use technology.
