Respuesta :

Answer:  C) 4.20

Explanation:

Multiply each value with its corresponding frequency:

  • 1*450 = 450
  • 10*35 = 350
  • 50*10 = 500
  • 100*4 = 400
  • 400*1 = 400

Add up the products

450+350+500+400+400 = 2100

Then divide this over the total frequency (450+35+10+4+1 = 500)

So we get 2100/500 = 4.20 as the expected value.
