Jake wants to find out what his customers think of his new recipe. which is the best group survey to find this information?

The second choice, "Assign every work hour a color on a spinner and ask all the customers that come in during the hour that the spinner landed on.  Repeat every day for a week."

Step-by-step explanation:

In order to get an unbiased result from a survey, we want the sample that we use to be as representative of the population as possible.

Going to a party his ex-bandmates are throwing will not necessarily represent all of his customers.

Comment boxes are voluntary response samples, which only gets information from people that feel strongly about the sample question.  This could lead to bias.

Asking customers that come in between 8 and 9 does not represent all of his customers, since other customers come in at different times of day.

This makes the second choice the best one.
