Based on these results, how many defective computers should be expected in the entire batch of 5500 computers?

Respuesta :

It's around 1 to 3

So

From 35 it's 1,2,3

From 5500 samples of 35

  • 5500/35≈157

Now

If 1 comes from each

  • 157(1)=157 detects

If 2

  • 157(2)
  • 314detects

If 3

  • 157(3)
  • 471 detects
