Question

There have been several complaints about a new MP3 player. The engineers at the factory that makes the MP3 player randomly select 294 players from the production line and find that 10 of them are defective. Based on the findings estimate the probability of the next MP3 player select it will be defective give your answer as a percentage and round to the tenths place

Answer 1

To estimate the probability of the next MP3 player being defective, we can use the concept of proportion. Based on a sample of 294 MP3 players, where 10 were defective, the estimated probability is approximately 3.4%.

Step-by-step explanation:

To estimate the probability of the next MP3 player being defective, we can use the concept of proportion. We know that out of a random sample of 294 MP3 players, 10 were defective. To find the probability of the next MP3 player being defective, we divide the number of defective MP3 players (10) by the total number of MP3 players in the sample (294). This gives us a proportion of 10/294. To convert this proportion to a percentage, we multiply it by 100. So, the estimated probability of the next MP3 player being defective is approximately 3.4%.
