A one-way ANOVA is appropriate when comparing the means of three or more groups. In this case, the researcher is comparing the average number of sales between stores in three different cities. Therefore, a one-way ANOVA is the most appropriate statistical test. The paired samples t-test would only be appropriate if the researcher was comparing the same stores before and after an intervention. The independent samples t-test would only be appropriate if the researcher was comparing the means of two independent groups. Finally, n-way ANOVA is not a valid statistical test.
