Question: More shoppers do their majority of grocery shopping on Saturday than any other day of the week.
A study cross-classified grocery shopping by age and major shopping day. The data were reported as percentage and no sample sizes were given.
| Major shopping day | Age | ||
| Under 35 | 35 - 54 | Over 54 | |
| Saturday | 24% | 28% | 12% |
| A day other than Saturday | 76% | 72% | 88 % |
Assume that 200 shoppers for each age category were surveyed.
Is there evidence of a significance difference among the age groups with respect to major shopping day?
