The conventional treatment for patients suffering from hypertension was found to be effective in 80% of all cases. A new treatment was tested on a sample of 400 patients suffering from hypertension and it was found to be effective in 340 of them.
1. Undertake an appropriate hypothesis test to determine if the new treatment is more effective than the conventional treatment (Note: You are expected to undertake perform tests at two levels.)
2. In the context of the above test, explain the meaning of Type I and Type II errors.

A research team is studying a new pain medication for patients suffering from fibromyalgia. Patients suffering from chronic pain as a result of fibromyalgia were divided into two categories: Treatment and Placebo. Patients in the treatment group were injected with the new drug while patients in the placebo group were injected with saline solution. Neither the patients, nor the health care practitioners admininstering the study knew who was receiving the actual drug. After two weeks the patients were asked to...

One treatment for patients suffering from widespread swelling (widespread accumulation of interstitial fluid; called "anasarca") is a two-pronged approach which involves: 1. Administration of exogenous albumin, a protein already found in high concentrations in the plasma, and 2. Administration of Lasix, a diuretic. Based on your understanding of filtration, reabsorption, and fluid homeostasis, why would this combination help remove accumulated interstitial fluid and contribute it to urine?

A sample of 15 patients suffering from asthma participated in an experiment to study the effect of a new treatment on pulmonary function. Among the various measurements recorded were those are forced expiratory volume (liters) in 1 second (FEV1) before and after application of the treatment. Suppose the researcher would like to test if the treatment is effective in increasing the FEV1. Please clearly state the hypotheses, carry out the test and state your conclusion for the tests listed below....

Cancer cells from a person suffering from malignant melanoma are analyzed and found to have an elevated ability to bind to laminin; they also secrete much higher than normal levels of a certain proteolytic enzyme activity. How would these differences from normal, control cells promote metastasis of these cancer cells?

3. A survey of 41 emergency room patients found that the average waiting time for treatment was 150 minutes with a standard deviation of s = 45 minutes. Find the 95% confidence interval of the population mean of wait times in the emergency room. We can be 95% confident that the mean waiting time for the emergency room is between ___________ and __________ minutes.
