O

A. True

O

B. False

Answer 1

A. True

Explanation:

You want to know if the same number of treatments should be applied to each of the groups in an experiment design using blocking to deal with extraneous factors.

Blocking

When certain characteristics of the experimental subjects are suspected of affecting the outcome of the experiment, subjects with those characteristics in common may be grouped in a "block."

When treatments are applied, the same treatments need to be applied uniformly across all blocks, so differences in outcome resulting from differences in block characteristics can be readily identified.

The same number of treatments should be applied to each of the groups — True.
