Answer:
To estimate the proportion of customers who were "good" with the customer service, we can calculate the sample proportion based on the given data. Out of the 10 randomly selected responses, we count the number of "good" responses and divide it by the total number of responses.
Given responses: Good, Good, Bad, Good, Bad, Good, Bad, Good, Good, Bad
Number of "good" responses: 6
Total number of responses: 10
Sample proportion of customers who were "good" with customer service:
Proportion = Number of "good" responses / Total number of responses
Proportion = 6 / 10
Proportion = 0.6
Therefore, based on the sample, we can estimate that approximately 60% of the customers were "good" with their customer service.
