To find the 98% confidence interval for the population mean, for a situation in which n is greater than 30, what Z value would you use? Hint: do not use the Z table or your calculator to find this value.

a) Find the 95% confidence interval of the true mean. b) Find the 98% confidence interval of the true mean. 3. A sample of 14 commuters in Chicago showed a mean commuting time of 33.2 minutes with a standard deviation of 8.3 minutes. how to make an essay look longer on google docs Hence we can invoke the Central Limit Theorem to determine a confidence interval for p. We use a slightly different standard error, though. The We use a slightly different standard error, though. The Confidence Interval for p is:
