See the attachment hope this helps.
3 x 25 = 75 and 3 x 5^2 = 75 are the same equations
72 x 5 = 360
2 x 3 x 7 = 42
the answer is
3 x 25 and 3 x 5^2

Answer:
B) A matched pairs design.
Because we satisfy the condition of randomized block design. We just have two treatment conditions (Method A and B) and the information can be grouped by pairs and the researcher define a blocking variable. And all the subjects are randomly assigned to the treatments.
Step-by-step explanation:
For this case we want to compare two methods preserving wood started with boards of southern white pine.
Let's analyze one by one the possible options for this case:
A) A block design.
False. In order to satisfy a block design we need to satisfy a placebo condition at some level, and that's not the case.
B) A matched pairs design.
Because we satisfy the condition of randomized block design. We just have two treatment conditions (Method A and B) and the information can be grouped by pairs and the researcher define a blocking variable. And all the subjects are randomly assigned to the treatments.
C) A probability sampling design.
False. That's a a method for select the sample but is not appropiate used when we want to select a design
D) A stratified random sample design.
False. That's a a method for select the sample but is not appropiate used when we want to select a design
I’m kind of in a rush so I’m not sure about these answers to be honest . But I THINK 7 is c?? And 8 might be 30? You might want to wait for someone else to answer just in case
