Describe a confidence interval for the mean of a population bystating 1. a population and a quantitative variable on thatpopulation, 2. a sample size, 3. a sample mean of that variable,and 4. a sample standard deviation, and 5. a confidence level, then6. finding the interval. Then perform a test of significance on themean of the population by stating 7. both a null and an alternativehypothesis and 8. an α-level, then finding 9. the one-samplet-statistic and either 10. rejecting or failing to reject the nullhypothesis. Remember that you do not need to list the values of thevariable for individuals in either the sample or the population,and that the values for 2, 3, 4, 5, and 8 do not need to becalculated, only stated.
