When the twosample

ttest is said to be robust, which of the properties does it not refer to?

A. In large samples, each sample larger than=40

n=40, outliers do not affect the

Pvalue.

B. In large samples, each sample larger than=40

n=40, the assumption of Normality for the population distribution is not necessary.

C. In large samples, each sample larger than=40

n=40, the population distributions can be skewed.

D. In large samples, each sample larger than=40

n=40, it is not necessary to have independent samples.
