Hi, recently I noticed that recent GRE practice papers seem to have more "D"s.

Is it statistically significant? If yes, I might consider "guessing D when in doubt"..

Expected mean of each option=np=66*1/5=13.2

Variance=npq=66*1/5*4/5=10.56

Standard dev.=3.25

GR0568:

"A"---11

"B"---14

"C"---11

"D"---16

"E"---14

GR9768:

"A"---11

"B"---13

"C"---13

"D"---16

"E"---13

GR9367:

"D"---17

GR8767 (anomaly):

"D"---13

## Higher percentage of option D ??
