SHOW ALL WORK. Interpret confidence intervals and explain the conclusions from hypothesis tests. For all hypothesis tests, clearly state the null and alternative hypotheses, the significance level, the test statistic, the p-‐value, and your conclusion. If you are using a t-statistic, clearly note how many degrees of freedom you have. 1.
