Question

The _____________ distribution would most likely be used to describe the distribution of time between arrivals of customers at the grocery store.

a) Normal
b) Exponential
c) Poisson
d) Binomial
e) Uniform

Answer 1

The Exponential distribution would most likely be used to describe the distribution of time between arrivals of customers at the grocery store. Option b

Step-by-step explanation:

The distribution that would most likely be used to describe the distribution of time between arrivals of customers at the grocery store is the Exponential distribution (option B).

The Exponential distribution is often used to model the amount of time until some specific event occurs. In this case, the event is the arrival of a customer. The Exponential distribution is characterized by the property of memorylessness, which means that the probability of an event occurring in the next time unit does not depend on how much time has already passed.

For example, if the average number of customers arriving per hour is 30, then on average, it takes 2 minutes for a customer to arrive. This can be calculated by dividing 60 minutes by the average number of customers per hour. Option b
