Using the Central Limit Theorem · Exercise 46
For each problem, wherever possible, provide graphs and use a calculator.
Certain coins have an average weight of 5.201 g with a standard deviation of 0.065 g. If a vending machine is designed to accept coins whose weights range from 5.111 g to 5.291 g, what is the expected number of rejected coins when 280 randomly selected coins are inserted into the machine?
