True

False

Respuesta :

Answer:  False

The "at least 8 failures" part is why this is false. If it said "at least 10 failures", then the statement would be true.

In terms of symbols we must have:

  • np ≥ 10 .... which represents at least 10 successes
  • n(1-p) ≥ 10 .... which represents at least 10 failures

where n is the number of trials and p is the probability of success of each trial.
