Answer:

  48

Step-by-step explanation:

Multiplying the ratio of raisins to M&Ms by 20, we find there are a total of 80 M&Ms in the bag.

 raisins : M&Ms = 1 : 4 = 20 : 80

The ratio of peanut to plain M&Ms is 2 : 3, a total of 2+3 = 5 ratio units. These stand for a total of 80 M&Ms, so each ratio unit of M&Ms stands for 80/5 = 16 M&Ms. That is ...

  peanut : plain = 2 : 3 = 32 : 48

There are 48 plain M&Ms in the bag.

Identify which of these designs is most appropriate for the given​ experiment: completely randomized​ design, randomized block​
Eduardwww [97]

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.
