Certainly! Let's fill in the blanks step-by-step:
1. Population: The population refers to the entire group of individuals Bart is interested in studying. In this case, Bart wants to know the preference of all his customers at his food truck. Therefore, the population consists of "all customers who eat at Bart's food truck."
First Drop-down: "all customers who eat at Bart's food truck"
2. Sample: The sample is the subset of the population that Bart actually surveyed. Since Bart surveyed a few of his friends who have eaten at his food truck, the sample consists of "Bart's friends who have eaten at his food truck."
Second Drop-down: "Bart's friends who have eaten at his food truck"
3. Conclusion: Based on the results from the surveyed sample, it is possible to make some inference. Here, the data shows that more friends prefer grilled sandwiches. Thus, it can be concluded that "more friends prefer grilled sandwiches."
Third Drop-down: "more friends prefer grilled sandwiches"
4. Improvement: To improve the accuracy of the results, Bart should consider surveying a larger and more diverse group. Therefore, the results would have been more accurate if Bart had surveyed "a larger and more random sample."
Fourth Drop-down: "a larger and more random sample"
To summarize, the filled-in statement would read as follows:
"In this case, the population consists of all customers who eat at Bart's food truck and the sample consists of Bart's friends who have eaten at his food truck. Based on the results, it can be concluded that more friends prefer grilled sandwiches. The results would have been more accurate if Bart had surveyed a larger and more random sample."
