In: Statistics and Probability
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.
