Drug A is the usual treatment for depression in graduate students. Pfizer has a new drug, Drug B, that it thinks may be more effective. You have been hired to design the test program. As part of your project briefing, you decide to explain the logic of statistical testing to the people who are going to be working for you.

Write the research hypothesis and the null hypothesis.

Then construct a table like the one below, displaying the outcomes that would constitute Type I and Type II error.

Write a paragraph explaining which error would be more severe, and why.

You are a cognitive psychologist who has developed a new treatment for depression. Currently, the most effective treatments for depression are behavioral treatments and pharmacological treatments (treatments involving medication). In order to validate your new treatment, you need to show that it is at least as effective as behavioral treatment and medication. You conduct a clinical trial to determine the effectiveness of your treatment by randomly assigning 60 individuals with depression to four treatment groups: a Control group (n =...

A company is research a new drug for cancer treatment. The drug is designed to reduce the size of a tumor. You are asked to test its effectiveness. You proceed to take samples from patients that are trying the drug. For each patient you take two measurements of its tumor, before and after the treatment. You want to see if the tumor's size has decreased. Assume the population distribution is normal and α = 0.05. The results of the samples...

You are a graduate student testing a new drug (drug G) that reduces cocaine addiction in mice. You want to find out what the pharmacological action of drug G is, and you know that it involves monoaminergic signaling, but you don’t know more about it than that. You have found a monoaminergic synapse whose signaling is affected by drug G. You can stimulate the presynaptic neuron at this synapse and record the resulting EPSPs in the postsynaptic neuron. This synapse...

Consider a new drug being developed for the treatment of a relatively common indication, such as diabetes mellitus or high blood pressure. In vitro and preclinical studies indicate the compound is extensively metabolized, primarily by CYP3A and partially by CYP2C19. The compound does not appear to be an inducer or inhibitor of any CYP450 enzymes, but it is a potential inhibitor of P-glycoprotein (P-gp). What in vivo drug-drug interaction (DDI) studies should the company developing the compound consider? A. A...

Suppose a researcher is interested in the effectiveness of a new respiratory treatment drug aimed at increasing forced vital capacity (FVC) among children with respiratory illnesses. In this study, each patient treated with the study drug is frequency paired with another patient on a number of characteristics treated with a placebo to insure independence among samples. Assume the following table represents the FVC for each participant and the paired control. Participant Treated with new drug FVC (%) Participant Treated with...
