Question

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

Please provide a simple and easy example with data.
