Final answer:
To find the relative frequency for the server with the least bills, one would use StatKey to analyze the 'Restaurant Server' dataset and calculate the frequency that server's bills represent out of the total number of bills.
Step-by-step explanation:
The question pertains to finding the relative frequency for the server who had the least bills from a dataset in a small bistro. This involves the use of StatKey or similar technology to analyze the dataset and calculate the relative frequencies. Using StatKey, one would go to the preloaded 'Restaurant Server' dataset, perform the analysis, and with the data obtained, identify the server with the lowest number of bills. The relative frequency is then found by dividing the number of bills for that server by the total number of bills in the dataset.
For instructional purposes, if the server with the least number of bills had 40 out of 157 total bills, the relative frequency calculation would be 40/157, which after rounding to three decimal places, might be 0.255, for example.
