a. Explanation Given info: A way to compare the lifetimes of 4 brands of batteries using 20 flashlights, is by randomly dividing the flashlights into 4 groups of 5 each and then randomly assigning the 4 groups to the 4 different brands of batteries. Justification: Completely randomized design : Completely randomized design is a design in which, each of the experimental units is randomly assigned to one of the treatments that is being studied in the experiment. It is the simplest form of experimental design. Randomized block design : Randomized block design is a design in which, the experimental units are first grouped into several ‘blocks’, based on their similarities of characteristics... b. To determine To explain: Whether the statistical design used is a completely randomized design or a randomized block design.
