Answer 1

The family of t distribution curves and the standard normal curve have means of 0 and 0 respectively

Answer: 0,0

Reason : Because t distribution and standard normal distribution both have symmetrical curves.

Also t distribution is for small samples with unknown population variances, and as the sample size increases, the the t distribution resembles to standard normal distribution and the mean od standard normal distribution is 0, therefore t distrubtion also have the mean 0.
