Justin is part of a group of students who are working with a bakery to collect marketing research. the bakery wants to determine whether a new type of pastry would be successful. justin's group decides to conduct a taste test and then have respondents fill out a survey about their thoughts. questions would include whether they liked or disliked the pastry, what they liked or disliked about it, and whether they would purchase it at certain price points. refer to scenario 4.1. justin and his team were hoping to conduct their tests in a grocery store. however, they could not receive permission to do so. in the end, they set up a booth in the student union building and asked passers-by to participate. to be more representative, they tried to divide by age and race to ensure they got enough from both genders and from different ethnicities. for instance, they know that roughly 5 percent of the student population at the school is hispanic. since its goal is to get 200 responses, they set a goal to ask 10 hispanic individuals to take the taste test. this is most likely an example of a. random sampling b. quota sampling c. stratified sampling d. crowdsourcing e. probability sampling
