Answer

Brief Explanations:

To get a representative sample of all his customers, Julio should survey customers at different times of day and different days of the week. Options 1 - 3 target specific subsets of potential customers (neighborhood - not necessarily customers, weekend - not weekday shoppers, morning - not other - time shoppers) and may introduce bias.
