Espafiol A consumer magazine is writing a story about the "convenience" of convenience stores. In particular, the magazine is comparing shopping durations at various convenience store chains. Shopping duration refers to the amount of time that elapses from the moment a customer enters the store to the moment he leaves the store. For each experimental scenario below, choose all tests that could be used for that scenario. Assume that the relevant assumptions for the populations (type of distribution, variance, etc.) are satisfied. Independent-samples t test (a) The magazine is comparing three chains of Dependent-samples t test convenience stores. For each chain, the magazine has chosen a different random sample of 12 shopping D One-way, independent-samples ANOVA durations. One-way, repeated-measures ANOVA Two-way (independent-samples) ANOVA Independent-samples t test (b) The magazine is comparing two chains of convenience Dependent-samples t test stores. It has chosen 18 pairs of adults, with the two adults In a pair having similar shopping habits. In each One-way, Independent-samples ANOVA pair, one adult visits one chain and the other adult visits the other chain. One-way, repeated-measures ANOVA Two-way (independent-samples) ANOVA (c) The magazine is comparing two chains of convenience Independent-samples t test stores. The magazine is trying to determine (1) If either of the chains tends to have shorter shopping durations Dependent-samples t test and (ii) if time of day of shopping-daytime versus nighttime-makes a difference. For each of the chains, One-way, independent-samples ANOVA the magazine has sampled 9 daytime shopping One-way, repeated-measures ANOVA durations at random and 9 nighttime shopping durations at random. Two-way (independent-samples) ANOVA
