The service times for customers coming through a checkout counter in a retail store are independent random variables with mean 1.5 minutes and variance 0.9025. Approximate the probability that 75 customers can be served in less than 2 hours of total service time.

Step 1
Given that the mean service time for one customer is 1.5 minutes, the expected total service time for 75 customers is: Expected total service time = 75 customers * 1.5 minutes/customer = 112.5 minutes Show more…

The amount of time that a customer spends waiting at an airport check-in counter is a random variable with mean 8.2 minutes and standard deviation 1.5 minutes. Suppose that a random sample of n = 49 independent customers is observed. Find the approximate probability that the average time waiting in line for these customers is (a) Greater than 10 minutes (b) Between 6 and 10 minutes (c) Less than 6 minutes

The amount of time (in minutes) a shopper spends browsing in the magazine section of a supermarket is a continuous random variable with probability density function $$f(t)=\frac{2}{25} t \quad(0 \leq t \leq 5)$$ How much time is a shopper chosen at random expected to spend in the magazine section?
