Initial Post Instructions
Describe a hypothesis test study that would help your work or conclusions in some way. Describe what variable would be tested and what would be your guess of the value of that variable. Then include how the result, if the null were rejected or not, might change your conclusions or actions in some way.

A hypothesis is a claim about a population parameter, such as ,u(population mean) or p (population proportion). In hypothesis testing, there are two hypotheses, the null hypothesis and the alternative hypothesis. Through the null hypothesis the claim always contains the condition of equality and the alternative hypothesis has 3 different possibilities. Within the healthcare world there are many different types of situations to evaluate for outcomes.  We have to test these hypotheses to help us intirate changes.
My hypothesis test that I would like to complete is if certification really improves patient outcomes. Does advanced certification help nurses provide better and safer care and are they necessary to work in critical care units? I would separate the group into nurses with advanced certification and nurses without advanced certification.  We would monitor the patient outcome from both sets of nurses and see if there was a difference in the care being provided.  Overall, this testing could be used to determine if critical care units want to enforce requirements for advanced certification in order to work in the units.
Overall, I think that the results may vary depending on a variety of things, such as experience, education level and facility and level of care provided. While advance certification is a great thing to have and most likely improves patient outcomes, I think these other factors may also play a big role. Because I have personally learned a lot of valuable information and skills throughout my career from nurses and other staff members with less education and less certification than myself.

Statistical Applications
Project for MA135 
You are doing research on balance and fitness. To complete this research you will need a watch with a second hand. Identify a random sample of n = 12 men and n = 8 women. You must answer this question: How do you establish that this sample is truly random?

 
Have each subject perform the following task:
a) Have the subjects stand with their hands at their side, raise one knee, cross their ankle over the other knee, squat and bring their hands palms together in front of their chest. Time the subject until they put their foot back down on the floor.
b) Ask the following questions:
i) How many days per week do they exercise?
ii) What is their favorite exercise?
You will analyze your data and compute the following statistics for each group:
1) The Mean and standard deviation of the number of seconds the subject stayed balanced
2) The Median number of days per week exercised
3) The Mode of the favorite exercise
4) The 90% confidence interval of the mean
5) Construct a complete hypothesis test and determine if the two groups have significantly different balance using α = 0.05.
Write a one page introduction to your research, discuss how you selected your sample (is it a random sample?), and write a one page conclusion. Present your data in an organized manner.
