Answer

The cumulative probability for a cherry tree height of 130 inches is \( \boxed{0.901} \).

Steps

Step 1 :Calculate the cumulative probability for a cherry tree height of 120 inches using the normal distribution with mean \( \mu = 112 \) inches and standard deviation \( \sigma = 14 \) inches.

Step 2 :The cumulative probability for a cherry tree height of 120 inches is \( \boxed{0.716} \).

Step 3 :Calculate the cumulative probability for a cherry tree height of 100 inches using the same normal distribution parameters.

Step 4 :The cumulative probability for a cherry tree height of 100 inches is \( \boxed{0.196} \).

Step 5 :Calculate the cumulative probability for a cherry tree height of 130 inches using the same normal distribution parameters.

Step 6 :The cumulative probability for a cherry tree height of 130 inches is \( \boxed{0.901} \).
