One major argument promoting the use of parametric tests over distribution-free tests is that parametric tests are
A) easier to calculate.
B) usually robust enough to be unaffected by violation of assumptions.
C) less affected by outliers than distribution-free tests.
D) used less frequently and therefore must be more elite.

Parametric tests are based on assumptions about the underlying population distribution, and violating these assumptions can result in incorrect conclusions. However, in many cases, parametric tests are robust enough to be reasonably accurate even when the assumptions are not exactly met. Distribution-free tests, on the other hand, do not make assumptions about the population distribution but may have less power and efficiency than parametric tests. Therefore, parametric tests are preferred when the assumptions can reasonably be met, as they are more powerful and efficient.
