Question

Teach for America Several programs attempt to address
the shortage of qualified teachers by placing uncertified
instructors in schools with acute needs—often in inner
cities. A 1999–2000 study compared students taught by

certified teachers to others taught by uncertified teach-
ers in the same schools. Reading scores of the students

of certified teachers averaged 35.62 points with standard

deviation 9.31. The scores of students instructed by uncer-
tified teachers had mean 32.48 points with standard devia-
tion 9.43 points on the same test. There were 44 students

in each group. The appropriate t procedure has 86 degrees

of freedom. Is there evidence of lower scores with uncer-
tified teachers? Discuss. (The Effectiveness of “Teach for
