Question

Glenda checks the computer monitors made at her company for defects. It has been shown that 0.5% of the monitors are defective. She decides to check several monitors and record if they are defective. Which of the following will make this process into a binomial experiment?
- Glenda checks the monitors until she has 300 defective monitors.
- Glenda checks 300 monitors and records the number that are defective until she gets greater than 0.5% defective monitors.
- Glenda checks the monitors until she has 300 non-defective monitors.
- Glenda chooses to check 300 monitors.

Answer 1

To be a binomial distribution the answer has to be a yes/no. (Defective/not defective)
She chooses 300 and records the answer defective/not defective.

Answer 2

Answer:

D is the correct answer.

Step-by-step explanation:

D. Glenda chooses to check 300 monitors.

A binomial experiment is defined as a statistical experiment which consists of n repeated trials. Only two possible outcomes are possible in each trial- either its a success or a failure. Here the probability of success remains the same on every trial.

Now, to know about the defects through binomial experiment Glenda must choose a number of computers or trials. So, option D is correct.
