However, after you have the data from the sample, you do have an idea of where the research hypothesis distribution of sample mean differences is located. What can you use to estimate the location of this distribution? Provide a specific value. (Hint: What value might represent the mean difference between the social pain scores of all those who took acetaminophen and all those who took the placebo if the research hypothesis is true?) . Specific value for the center of the research hypothesis distribution of sample mean differences = D Question 18 1 pts
