Answer: D. To produce treatment groups with similar characteristics
Step-by-step explanation:
By using randomization in sampling, the Sample would be more representative of the Population it is based off of because different demographic characteristics may be picked.
This leads to a situation where the groups have similar characteristics between themselves thereby making it easier for comparison. For example, Group 1 would have certain types of people that will be represented in Group 2 and Group 3 as well. That way the effects of the drug can be properly studied as it affects different people. For instance, say there are 4 obese people in a sample of 10, instead of group one having all obese people, randomization may be able to give group one, 2 obese people and 2 obese people to group 2 as well. That way when comparing, the effects of the drug on the two groups is easier to be compared because the two groups have similar people.
Answer:
slope is -2/3
Step-by-step explanation:
The answer is Equally Likely because there’s both 3 even numbers and odd numbers on a cube/dice.
Rule= (x,y) is now (y,x) so coordinates of (5,4) now would be (4,5). this is the rule for y=x problems so you take the coordinates and flip them for every point.
