Cindy is the quality control specialist for a microphone manufacturing company. Every month, she will need to test 200 microphones with a sound pressure system.

Each microphone should have the average sound pressure level around 100 dB with a standard deviation of 0.025 dB. The sound pressure level gives a bellshaped distribution and the company rejects any microphones that are more than two standard deviations from the mean. Determine how many microphones will be rejected on average from the 200 microphones.
