Question
43. 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.
