Question 1

Pew Research reports that 63% of the U.S. adult cell phone owners use their phone to go online. A company wants to target 16- to 24-year olds for advertising and they wonder if that age group has a similar pattern of phone use.

Should the company conclude that the percentage of cell phone owners in this age group who use their phone to go online is different from 63%? Explain.

Question 2

A report on health care in the US said that 28% of Americans have experienced times when they haven't been able to afford medical care.  A news organization randomly sampled 801 black Americans, of whom 38% reported that there had been times in the last year when they had not been able to afford medical care.  Does this indicate that this problem is more severe among black Americans?
