The distribution of ages for all Oscar winning actors at the time they receive the award is approximately normal with a mean of 44 years and standard deviation of 9 years.

The oldest actor to win the Oscar was Henry Fonda at age 76 for his performance in ‘On Golden Pond’. What percent of actors received the Oscar after the age of 70? Label and shade the picture of the area that represents this percentage below. You will notice that it is a right-tailed area.
