The following question is based on a research context adapted from the research by You et al. 2020 fromJournal of Marketing. You will encounter more than one question based on this research context. Thus, for your convenience, the research context below will be repeatedly presented when you encounter other questions related to this research context.

According to the research question, please indicate which of the following hypotheses is RIGHT?

		H0: Recovery strategy does not influence tipping behavior.
		H0: Customer's tipping behavior does not change regardless of what strategy (i.e., say "Thank you" vs. "Sorry") the service provider uses.
		H1: Recovery strategy influences customers' tipping behavior. Specifically, saying thank you (vs. sorry) may increase or decrease tipping likelihood or amount.
		All of the above are right.

2. The following question is based on a research context adapted from the research by You et al. 2020 fromJournal of Marketing. You will encounter more than one questions based on this research context. Thus, for your convenience, the research context below will be repeatedly presented when you encounter other questions related to this research context.

The researcher conducted data analyses to examine the association between recovery strategy (appreciation vs. apology) and tipping likelihood. The researcher reported that the average tipping likelihood in the appreciation condition is 4.87, the average tipping likelihood in the apology condition is 3.94, t-value = 5.27, and critical value = 2.16. Based on the reported statistical results ( 5% significance level), which of the following statements must beWRONG?

		The test the researcher conducted should be one-sample t-test.
		Based on the results, the researcher should conclude that appreciation leads to a higher tipping likelihood at 5% significance level.
		The researcher can conclude that saying "Thank you" is superior to saying "Sorry" in service failure contexts.
		The results suggest that the researcher should reject the null hypothesis.
