Weba. For a fixed confidence level, when the sample size increases, the length of the confidence interval for a population mean decreases. True . b. The z score corresponding to a 98 percent confidence level is 1.96. False, for 98% confidence z = 2.33 . c. The best point estimate for the population mean is the sample mean. True . d. An example of how is used is to make confidence intervals of the unknown population mean. If the sampling distribution is normally distributed, the sample mean, the standard error, and the quantiles of the normal distribution can be used to calculate confidence intervals for the true population mean. The following expressions can be used to calculate the upper and lower 95% confidence limits, where is equal to the sample mean, is equal to the standard error for the sampl… WebThanks for contributing an answer to Cross Validated!
