Refer to Exercise 4.4.3. Find the number of customers, m, such that the probability that all the m customers can fill up in less than 3 hours is approximately 0.2.
Refer Exercise 4.4.3
The times spent by customers coming to a certain gas station to fill up can be viewed as independent random variables with a mean of 3 minutes and a variance of 1.5 minutes. Approximate the probability that a random sample of 75 customers in this gas station will spend a total time less than 3 hours. Interpret your results and state any assumptions.
