Final answer:
Calculating the average sales for cluster 6 involves summing the sales and dividing by the number of dining options in the cluster, then comparing this figure to the overall population average across all restaurants.
Step-by-step explanation:
To describe the average sales of cluster 6 for each type of dining option compared to the overall population average, one would first need to calculate the mean number of sales within cluster 6. This involves summing the total sales for the cluster and dividing by the number of dining options in cluster 6. Then, compare this average to the overall average sales across all clusters and restaurants.
For example, if cluster 6 had three types of dining options with sales totaling 100, 85, and 90 respectively, the average sale for cluster 6 would be (100+85+90)/3 = 91.67. To compare it to the overall average, suppose the average across all restaurants was 75; cluster 6's average of 91.67 would be higher than the overall average.
