Final answer:
The term 'minimum tolerable expectation' refers to the lowest level of acceptable service, yet the question asks for a hypothesis test to determine if a single line reduces waiting time variation in a business setting at a 5 percent significance level.
Step-by-step explanation:
The phrasing 'minimum tolerable expectation' refers to the lowest level of service quality that a customer is willing to accept, which in a business context could be termed 'basic service'. However, the actual question relates to a statistical hypothesis test, asking to test the claim that a single line causes lower variation among waiting times for customers. To test this, you would collect data on customer waiting times from both a single line system and multiple lines system and perform an appropriate statistical test, such as a variance comparison test or an ANOVA, with a significance level of 5 percent. If the p-value obtained from the test is less than the 5 percent significance level, then you would reject the null hypothesis (that there is no difference in variation), supporting the claim that the single line system has lower variation in waiting times.
The service that represents the minimum tolerable expectation, or the bottom level of performance acceptable to the customer, is called the minimum viable service. It refers to the basic level of service that a customer expects from a business or organization. This level of service is essential to meet the customer's needs and maintain customer satisfaction.For example, in the restaurant industry, the minimum viable service would include factors such as prompt seating, a clean environment, courteous staff, and timely delivery of food. If these basic expectations are not met, it can lead to dissatisfied customers and negatively impact the business.It is important for businesses to not only meet but also exceed the minimum viable service to create a positive customer experience and build customer loyalty.
