Quizplus · Accepted Answer

Since we are trying to determine if the average price of imported wine is less than the average price of domestic wine, we need to perform a one-tailed t-test with unequal variances. Using a calculator or statistical software, we can calculate a t-value of -2.54 with 27 degrees of freedom and a significance level of 0.05. Therefore, the appropriate test value for a t test is -2.54.
