In 2006, 25.7% of all live births in the United States were to mothers under 20 years of age.  A sociologist claims that births to mothers under 20 years of age is decreasing.  She conducts a simple random sample of 70 births and finds that 16 of them were to mothers under 20 years of age.  Test the sociologist’s claim at the α = 0.2 level of significance. (a) Formulate the null and alternative hypotheses.
