Calcium is the most abundant mineral in the human body and has several important functions. Most body calcium is stored in the bones and teeth, where it functions to support their structure. Recommendations for calcium are provided in Dietary Reference Intakes, developed by the Institute of Medicine of the National Academy of Sciences. The recommended adequate intake (RAI) of calcium for adults (ages 19-50 years) is 1000 milligrams (mg) per day. Suppose that we want to perform a hypothesis test to decide whether the average adult with an income below the poverty level gets less than the RAI of 1000 mg. a. Determine the null hypothesis for the hypothesis test. b. Determine the alternative hypothesis for the hypothesis test. c. Classify the hypothesis test as two tailed, left tailed, or right tailed.

1. Calcium is the most abundant mineral in the human body and has several
important functions. Most body calcium is stored in the bones and teeth, where it
functions to support their structure. Recommendations for calcium are provided
in Dietary Reference Intakes, developed by the Institute of Medicine of the
National Academy of Sciences. The recommended adequate intake (RAI) of
calcium for adults (ages 19-50 years) is 1000 milligrams (mg) per day. Suppose
that we want to perform a hypothesis test to decide whether the average adult
with an income below the poverty level gets less than the RAI of 1000 mg.
a. Determine the null hypothesis for the hypothesis test.
b. Determine the alternative hypothesis for the hypothesis test.
c. Classify the hypothesis test as two tailed, left tailed, or right tailed.
