1. A machine is used to shape plastic toys. When the machine is adjusted and working well, it still produces about 11% defective toys. The toys are manufactured in lots of n = 100. Letr be a
random variable representing the number of defective toys in a lot. Then p-hat = r/n is the
proportion of defective toys in a lot. 1) Explain why p-hat can be approximated by a normal
random variable.
