Rounds, Katina Lorette: Unit Three Discussion - One Sample Hypothesis Tests........(Dec 2 2013 8:42AM)
A. Variable – The variable from my organization is the time frame it takes to process test results. The process time for receiving test results solely depends on the complexity of the test being performed. However, some tests might take a few hours to as much as several days before results are ready.
B. One Sample Hypothesis – The hypothesis is the more lab tests that are perform on specific patients than the more time it will take for the test results to come back. Example- The lab took a random sample from the lab data population and compares it to the sample proportion to the population proportion. The sample size included 250 patient test results with 150 number of success of patients.
C. Description of the test you are using (either mean or a proportion) – I would perform the proportion test.
D. Description of why are you using this particular test - I would use proportion because its shows the difference between the population proportion of the patient’s and the current proportion of the patients time frame for lab tests. It’s also provides useful information about knowing the proportion of successes in the population. A hypothesis test for proportions measures the proportions of members with the characteristic in one or more samples from the population in order to gauge the proportions that exist in the population itself Caffo (2000).

Anita, your use of age as your variable choice in the discussion post would fit the criteria for the hypothesis testing. Determining the age at which motivational levels start to...
