The age of all farmers are normally distributed with a mean 48 years old and standard deviation 12 years old.

Part A
About % of all farmers are older than 16 years old.
(Rounding the percentage to 2 decimal places if possible)

Part B
About % of all farmers are younger than 38 years old.
(Rounding the percentage to 2 decimal places if possible)

Part C
About % of all farmers are between 28 years old and 61 years old.
(Rounding the percentage to 2 decimal places if possible)

Part D
About 4% of all farmers are older than years old.
(Rounding the answer to 3 decimal places if possible)

Part E
About 86% of all farmers are younger than years old.
(Rounding the answer to 3 decimal places if possible)

Part F
About middle 73% of farmers between years old and years old.
(Rounding the answer to 3 decimal places if possible)
