We determined that it makes sense to consider a one-sample t test for a population mean, using the five-step process for hypothesis testing problems. The first step is Hypotheses. Determine the null and alternative hypotheses. The question is whether the mean price of a Big Mac in Europe is less than the U.S. price ($5.04), which translates to an alternative hypothesis of v5.04.
