Question
A sample of 150 flash drives contained 7 defective drives. How many defective flash drives would you expect in a batch of 2700 flash drives?
Step 1
This is done by dividing the number of defective drives (7) by the total number of drives (150). This gives us the proportion of defective drives in the sample. \[ \text{Proportion of defective drives} = \frac{7}{150} \] Show more…
