Answer:

Part a:

Show the probability density function for the waiting times at Kroger, assuming they are exponentially distributed.

Solution:

Probability density function f(x) = (1/ )*e-x/  = (1/26)*e-x/26 (result)

Part b:

Calculate the probability that a customer waits between 15 and 30 seconds.

Solution:

0.2462

Part c:

Determine the probability that a customer must wait longer than 2 minutes.

Solution:

0.0099

Explanation:

All calculations are included.

Answer:

a) the small bus

b) the medium or large bus

c) the small bus

Explanation:

a) using the maximin criterion, the manager aims to maximize the least possible profit (a pessimistic approach), which results in the following profits:

Bus size Demand

Low Medium High

Small 50 60 70 → minimum profit = 50

Medium 40 80 90 → minimum profit = 40

Large 20 50 120 → minimum profit = 20

Thus, the optimal choice yielding the highest minimum profit is the small bus.

b) applying the maximin criterion, the manager will seek to minimize potential maximum losses, determining losses based on the best profit scenario:

Bus size Demand

Low Medium High

Small 0 -20 -50 → maximum loss = -50

Medium -10 0 -30 → maximum loss = -30

Large -30 -30 0 → maximum loss = -30

Hence, the option that bears the least maximum loss is either the medium or large bus.

c) for calculating the expected value of each option:

small = 30/100*50 + 30/100*60 + 40/100*70 = 61

medium = 30/100*40 + 30/100*80 + 40/100*90 = 72

large = 30/100*20 + 30/100*50 + 40/100*120 = 69

The small bus turns out to be the best choice, as it has the highest expected profit.
