The table shows population statistics for the ages of Best Actor and BestSupporting Actor winners at an awards ceremony. The distributions of theages are approximately bell-shaped. Compare the z-scores for the actors inthe following situation.Best ActorBest Supporting Actorμ = 53.0μ=42.06=8.8o=12In a particular year, the Best Actor was 44 years old and the Best SupportingActor was 40 years old.Determine the z-scores for each.Best Actor: Z =Best Supporting Actor: z =(Round to two decimal places as needed.)

X~N( μ , ?)For best actor μ= 42 , ?=8.8For best supporting actor μ= 53 , ?=12Z-score =( x - μ )/?
