Suppose you want to test whether the average amount of education is 14 years at the =0.05 level.

What assumptions do you need to use the one-sample t-test? Do you think the data meet the assumptions?

What is the null hypothesis you want to test? The alternative hypothesis?

• Test the hypothesis and make summary of your conclusions. Be specific. Mention your conclusion, test statistic value, p-value, alpha level, etc. and put the conclusion into proper context.

What is the 95% confidence interval for the average years of education? How does it differ from the 95% confidence interval for the t test? (Hint to get 95% CI for mean you must run Explore).

• Based on the 95% confidence interval for the mean years of education can you reject the null hypothesis that the average amount of education is 14 years? Explain.

• Based on the confidence interval for the mean, what is a plausible range of population values for average amount of education?
