Answer:
Lyrics A) c b a
Step-by-step explanation: We know about tails in the three mentioned distribution
Standard normal distribution N ( 0 . 1) is a bell shape curve, simmetrically distributed at both sides of the zero value (mean ) very, very long tiles and very thin too
On the other side t -student distribution is a family of curves all of them much more flat than SND and much much thick at the tails.
When degrees of fredom in t -student distribution is high t-student distribution will appear more and more close to SND
Therefore the order is c b a
