A random sample of size 10 from Plastic 1 is taken and a random sample of size 7 is taken from Plastic 2. Plastic 1 had a sample mean breaking strength of 150.0 psi and a sample standard deviation of 1.5 psi. Plastic 2 had a sample mean breaking strength of 148.0 psi and a sample standard deviation of 1.3 psi. The company will use Plastic 1 if its mean breaking strength is larger than the mean breaking strength of Plastic 2. Hypothesis testing will be used.
