Iron is an integral part of many proteins and enzymes that maintain good health. Recommendations for iron were developed by an institute of medicine for a certain region. The recommended dietary allowance (RDA)of iron for adult females under the age of 51 years is 19 milligrams (mg)per day. A hypothesis test is to be performed to decide whether adult females under the age of 51 years are,on average,getting

less than the RDA of 19mg of iron per day. Complete parts (a)through (c).
