A store asked 250 of its customers how much they spend on groceries each week. The responses were also classified according to t
he gender of the customers. We want to study whether there is a relationship between amount spent on groceries and gender. A meaningful display of the data from this study would be
o side-by-side baxplots
O a pie chart
O a histogram
O a scatterplot
O a two-way table
Side-by-side boxplots are the appropriate display for comparing several groups of quantitative data (in other words, for displaying the relationship between a categorical explanatory variable, in this case "gender," and a quantitative
response variable, in this case "amount spent on groceries").
