For example, for a significance level of 5%: - For an upper-tail test, the critical value is the 95th percentile of the t-distribution with n— 1 degrees of freedom; reject the null in favor of the alternative if the t-statistic is greater than this. - For a lower-tail test, the critical value is the 5th percentile of the t-distribution with n— 1 degrees of freedom; reject the null in favor of the alternative if the t-statistic is less than this. 5th percentile. HYPOTHESIS TESTING 21 As previously, it is perhaps easier to see how all this works by example.

We could extend this analysis to see if there are any features related to the homes that could help us to understand variation in sale prices. For example, it is likely that there is an association between the sale price (in thousands of dollars) for a particular single-family home and the corresponding floor size (in thousands of square feet). It makes more sense to think of sale price as "responding" to floor size rather than the other way around, so we should set the response variable, Y, as sale price, and the predictor variable, X, as floor size.
