Question

consider two grocery stores at which the mean time in line is the same but the variation is different. at which store would you expect the customers to have more complaints about the waiting time? explain.

choose the correct answer below.

a. the customers would have more complaints about the waiting time at the store that has more variation because some customers are easily annoyed.

b. the customers would have more complaints about the waiting time at the store that has more variation because some customers would have longer waits and might think they are being treated unequally.

c. the customers would have more complaints about the waiting time at the store that has less variation because some customers are easily annoyed.

d. the customers would have more complaints about the waiting time at the store that has less variation because some customers would have longer waits and might think they are being treated unequally.

Explanation:

Variation in waiting - time implies differences in individual waiting - times. A store with more variation means some customers will have much longer waits than others. Customers with longer waits may feel they are being treated unequally compared to those with shorter waits, leading to more complaints. Option A's reason about customers being "easily annoyed" is too vague. Options C and D are incorrect because a store with less variation has more consistent (and likely fairer - seeming) waiting - times.

Answer:

B. The customers would have more complaints about the waiting time at the store that has more variation because some customers would have longer waits and might think they are being treated unequally.
