Two individual staff members were being observed performing identical activities in the Doctor's office. 25 random samples were taken. One of the Medical Assistants is a new employee. Medical Assistant #1 has been with Dr. Deasley for several years. Medical Assistant #2 is a new employee and has been with this medical practice for 9 months. We want to determine how Medical Assistant #2 performs when compared to Medical Assistant #1 since she is a new employee.(SEE APENDIX E for data sets)

Assume this is a one-sided t-test and the historical average of Medical Assistant #1 is .0126

Medical Assistant #1 data will be considered the population mean

Please provide the following information based on your analysis of the two Medical Assistants

Medical Assistant #2 Average

Medical Assistant #2 Standard Deviation

Null Hypothesis

Alternative Hypothesis

T-Test Statistic

Critical Value

Statistical Conclusion for the null and alternative hypothesis.

Conclusion of Analyze: Stem and Leaf Plots were created; Measures of Central Tendency were also determined, and an interpretation of the results were made. Data was analyzed to review if different staff members were performing similarly or not.Students should have established a Null Hypothesis and Alternative Hypothesis from the data for the 2 staff members. A one-sided T-Test was performed, and conclusions made based on the outcome.
