The data and an incomplete ANOVA table are shown below. A market researcher is studying the spending habits of people across age groups. The amount of money spent by each individual is classified by spending category (Dining out, Shopping, or Electronics) and generation (Gen-X, Gen-Y, Gen-Z, or Baby Boomers) . The data and an incomplete ANOVA table are shown below. Which of the following are the competing hypotheses for the hypothesis test about the interaction? A) H<sub>0</sub>: There is interaction between spending category and generation, H<sub>A</sub>: There is no interaction between spending category and generation. B) H<sub>0</sub>: μ<sub>1</sub> = μ<sub>2 </sub>= μ<sub>3,</sub> H<sub>A</sub>: Not all population means are equal. C) H<sub>0</sub>: There is no interaction between spending category and generation, H<sub>A</sub>: There is interaction between spending category and generation.
