Final answer:
The term 'standard deviation' represents the consistency of the fry weight served at Frenchies. The observed standard deviation from the sample was 2 ounces, not 1.5 as the chef claimed, indicating inconsistency.
Step-by-step explanation:
The standard deviation for a perfect Five Guys fry can change from shift to shift. In the scenario provided, the chef of Frenchies claims that the standard deviation for a 10-ounce order of fries is at most 1.5 ounces, but after a sample of 49 orders is analyzed, the actual standard deviation is found to be 2 ounces. This evidently suggests that there is more variability in the weight of the French fry orders than the chef thought.
Since the manager is concerned with consistency, the observed standard deviation being greater than what is claimed by the chef indicates a potential issue in quality control. It is important to resolve this to ensure that patrons receive a consistent amount of French fries with their order.
