Question 2

Which type of study best describes the following research most likely to be done?  

A researcher is testing new weight loss supplements. The researcher decides to sample two groups. The first group of subjects, the researcher labeled group 'A'. The researcher plans to give a placebo that looks like the real medicine but is just a sugar pill to Group 'A'. The second group, group 'B', will be given the real medicine. The researcher knows which participants got the placebo and which received treatment but the participants don't know.

Question 3

A person is studying a new headache medicine that has been deemed safe for human trials. The researcher offers the new medicine to people suffering from headaches at several local hospitals. The researcher has decided to use a blind study and form 2 sample groups. He gives patients in Group A the actual real experimental medicine. He gives patients in Group B a fake treatment that is nothing more than a sugar pill that looks like the real medicine.  

How would you describe Group B?  

Placebo Group

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
