Solution Steps

Step 1: Determine the nature of plastic

Plastic is a material that does not allow the free flow of electric charge. It is commonly used as an insulating material in various applications.

Step 2: Determine the nature of water

Pure water is a poor conductor of electricity. However, water found in nature typically contains dissolved salts and minerals, making it a conductor.

Step 3: Determine the nature of glass

Glass is a material that does not conduct electricity under normal conditions. It is used as an insulator in many electrical applications.

Step 4: Determine the nature of copper

Copper is a metal and is well-known for its excellent electrical conductivity. It is widely used in electrical wiring and components.

Final Answer

  1. Plastic: \(\boxed{\text{insulator}}\)
  2. Water: \(\boxed{\text{conductor}}\)
  3. Glass: \(\boxed{\text{insulator}}\)
  4. Copper: \(\boxed{\text{conductor}}\)

Find the necessary sample size. You wish to estimate the mean weight of machine components of a certain type and you require a 95% degree of confidence that the sample mean will be in error by no more than 0.009 g. Find the sample size required. A pilot study showed that the population standard deviation is estimated to be 0.02 g.
