In a Paired Samples Design, High Socialist (HS) Countries Were $\alpha$

Multiple Choice

In a paired samples design, High Socialist (HS) countries were compared to Low Socialist (LS) countries. On the Quality Index (QI) the HS scored 77 and the LS scored 73. A two-tailed test with a $\alpha$ level of .05 was adopted. A t value of 2.30 was found. Which conclusion follows?

A) If df = 7, HS have a higher QI than LS.
B) If df = 7, LS have a higher QI than HS.
C) If df = 30, LS and HS are not significantly different in QI.
D) If df = 10, HS have a higher QI than LS.
E) If df = 10, LS have a higher QI than HS.
