Answer:
Option E
Step-by-step explanation:
Single-blinding refers to a kind of clinical trial in which only the researcher conducting the study knows which treatment or the participant is receiving until the trial is over.
Control Group refers to the group in an experiment that does not receive treatment by the researchers, it is used as a benchmark to measure how the other tested subjects do.
Under the random assignment, the study participants are randomly allocated to different groups, such as the experimental group, or treatment group.
Confounding can be controlled by adjusting for it after completion of a study using stratification or multivariate analysis.
The treatment group refers to the experimental groups that receive treatment in an experiment. The “group” is made up of test subjects (people, animals, plants, cells, etc.) and the “treatment” is the variable under study.
Since here we are making groups to perform the experiment away from the main workforce, the feature used here is the treatment group.
in 20 days 4 half life will be completed

formula :-
Answer:
1/2 x 2/3 = 0 . 3
1 1/2 x3/4 = 1. 125
4/4 x 7/6 = 1 . 27
3 divided by 1/2 = 6
2/3 divided by 1/2 = 1. 3
Step-by-step explanation:
1/2 x 2/3
= 0.33333333333
= 0 .3
1 1/2 x3/4
= 1.125
4/4 x 7/6
= 1.16666666667
= 1.27
3 divided by 1/2
= 6
2/3 divided by 1 / 2
= 1.33333333333
= 1. 3
Hope this answer helps you :)
Have a great day
