You wish to test whether a particular drug manages to bring body temperature down. So, you conduct a pilot study where 47 people receive the drug, and 45 people receive a placebo.  The body temperatures of patients from the treatment group are group 1 (variable X1);  those from the placebo group are group 2 (variable X2). What is the research hypothesis? mu1 > mu2 mu1  ≠  mu2 mu1 < mu2 mu1 = mu2

Question

You wish to test whether a particular drug manages to bring body temperature down. So, you conduct a pilot study where 47 people receive the drug, and 45 people receive a placebo. 

The body temperatures of patients from the treatment group are group 1 (variable X1);  those from the placebo group are group 2 (variable X2).

What is the research hypothesis?

mu1 > mu2
mu1  ≠  mu2
mu1 < mu2
mu1 = mu2
Expert Solution
Step 1

Given information-

No. of people receive the drug, n1 = 47

No. of people receive a placebo, n2 = 45

We have to test the claim that whether a particular drug manages to bring the body temperature down.
