175 is the answer
The value of 9 in 49.21 is 9.00
but the value of 9 is 982.3 is 900
Answer:
Completely Randomized Design
Step-by-step explanation:
In a completely randomized design, the samples are randomly assigned to the treatment without creating any blocks or groups.
Like here, in the given scenario, we do not have to divide subjects in two groups as they are all same.
Whereas, in a randomized block design, the participants are divided into subgroups in a way, that the variability within the blocks is less than the variability between blocks.
After dividing, the participants within each block are randomly assigned to treatment conditions.
Hence, the completely randomized design is used here.
