You are investigating if knee diameter increases with osteoarthritis (OA)-associated inflammation. Each patient has one contralateral control (healthy) knee and one knee with severe osteoarthritis. You are interested in determining with 95% confidence if osteoarthritis increases (hint: use the correct alternate hypothesis) joint swelling in OA knees in comparison to their contralateral control knee. Write the null and alternate hypothesis and determine if there is a significant difference in Knee Diameter with and without OA.

	Knee Diameter (cm)
	Contralateral Control	OA Knee
Patient 1	16	18
Patient 2	24	28
Patient 3	22	25
Patient 4	10	12
Patient 5	24	27
Patient 6	17	19

Expert Solution

Let difference, d=OA Knee - Contralateral Control

The hypotheses are:

Enter data in excel.

Click on Data->Data Analysis.

Click on t-Test: Paired Two Sample for Means.

Enter both data ranges and click ok.

The output is shown below:

Since p-value = 0.000 is extremely small, reject the null hypothesis. With 95% confidence, we can conclude that osteoarthritis increases joint swelling in OA knees in comparison to their contralateral control knee.

For each scenario below, outline the appropriate patient teaching you would perform. Osteoarthritis An established patient with a history of osteoarthritis is undergoing ongoing therapy, which includes drug therapy and gentle exercise regimen. The patient is discouraged because of increased pain and loss of mobility. The physician instructs you to provide printed information regarding therapeutic diets and exercise for the patient. In addition, you are to review intended effects of the prescribed drug therapy. How do you handle this patient-teaching...

Researchers conducting a clinical trial randomly assigned 60 patients with painful knee osteoarthritis evenly into one of three treatment groups: glucosamine, chondroitin, or placebo.After the study period, patients were asked if they experienced substantial improvement in pain and ability to function normally.Thirty-four patients replied that they did have an improvement, including 13 in the glucosamine group, 16 in the chondroitin group, and 5 in the placebo group. List a potential confounding variable for this study and briefly explain a possible...

You are reading a research study where the researchers are investigating osteoarthritis pain. In the study, subjects are given either an anti-inflammatory drug injection or a saline injection to reduce osteoarthritis joint pain. A study subject reported that since she received her study injection, her arthritis pain does not seem to have improved. In fact, her pain is getting worse. What is a possible reason for her continued osteoarthritis pain? The research subject likely received the anti-inflammatory study drug, but...

A bank teller serves customers one at a time so that each customer has an associated ‘service time,’ or time during which they interact with the teller. We know that the service times are not Normally distributed as some customers have very long service times. However, we do know that service times have a mean of 4 minutes and standard deviation of 1.2 minutes. What is the probability that a sample of 40 bank customers has an average service time...
