Answer:
b. To increase the accuracy of the research and prevent skewness in the idea.
Step-by-step explanation:
Random assignment ensures that any difference between groups recorded at the end of an experiment can be attributed to the experimental procedures. It refers to how you arrange the participants into required groups (different treatment and control groups). In the case of non-random assignment, the two major problems are generalisation of results and bias, which could lead to skewness in the idea of the experiment.
One of the importance of random assignment in this given experiment is to increase the accuracy of the research and prevent skewness in the idea.
6 dozen were purchased

number purchased = 
= 6
Answer:
Step-by-step explanation:
Hello there!
If DEF = 18, we then use the sin method, or the law of sin.
18 divide by sin90 would be F = sin45 .
We therefore end up with 12.72 but rounded would be 12.7 as 2 is lower than 5, so, it just rounds back down to 7.
Your answer: 12.7
