1. Suppose that hemoglobin in the blood should be 12 for a person not to be anemic. It is suspected that a certain population of children has an average hemoglobin level less than 12 (and therefore is anemic on average). A random sample of 50 children from this population gave a sample mean of 11.3 and a standard deviation of 1.6.
d). 1pt.What conclusion do we reach? Use the 5% level of significance. (State conclusions in words a non-statistician would understand).
e). 3pts.What would be the critical value and conclusion if we did a two-sided test?

1.A person with high blood cholesterol should consider
participating in an aerobic exercise program such as walking or
jogging because aerobic exercise
A.
will raise HDL ("good") cholesterol after a period of training
and decrease the risk for heart disease.

waste elimination.

Increasing hemoglobin in the blood increases the density. This
is the basis for a simple test that can be used to see if a
prospective blood donor has high enough hemoglobin levels to safely
donate blood. A drop of blood is placed in a copper sulfate
solution and the time for the drop to sink to the bottom is
measured. If the time to sink to the bottom is too long, the
hemoglobin level is too low. Explain how this...
