Answer #1

The answer is -B. Kruskal-Wallis H.

RATIONALE-

An important assumption when we consider the one-way ANOVA is that the population under consideration is Normally distributed.When,this assumption for a parametric one-way Anova is not met,we should find another non-parametric approach by which we can test our desired hypothesis.

Kruskal-Wallis H is one of them.It is a non-parametric approach to test whether the samples comes from the same population or not.The desired hypothesis is same as ANOVA,implying it is a very good alternative when the required conditions for one-way ANOVE is not met.(ANSWER)

Parametric statistical procedures are based on a number of "statistical assumptions" that need to be met in order for the conclusions drawn to be valid. One of these statistical assumptions is that the distribution of the population data from which the sample is drawn meets the definition of a “normal distribution”. A first step in data analysis is to first check to see if there is evidence that the statistical assumptions have been met. This involves the researcher reviewing the...

This means you must...
