Question
A study reports that recent college graduates from New Hampshire face the highest average debt of $31,813 (The Boston Globe, May
27, 2012). A researcher from Connecticut wants to determine how recent undergraduates from that state fare. He collects data on debt
from 40 recent undergraduates. A portion of the data is shown in the accompanying table. Assume that the population standard
deviation is $5,000. [You may find it useful to reference the z table.)
