MHA-FPX5017 Assessment 2 Instructions– Hypothesis Testing for Differences Between Groups
Overview
Perform hypothesis testing on the differences between two groups and create an Excel document. Write a 2–3-page analysis of the results in a Word document and insert the results into this document.
Note: You are strongly encouraged to complete the assessments in this course in the order they are presented.
Hypothesis testing is a foundational statistical technique used to make decisions about a hypothesis. A hypothesis test compares two mutually exclusive statements (null hypothesis, alternative hypothesis) where only one is true. Hypothesis testing can determine statistical significance by examining the probability that a given result would occur under the null hypothesis. For this assessment, you will perform hypothesis testing on the differences between two groups.
By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:
Competency 1: Plan for data collection, measurement, and analysis.
Generate a hypothesis about the difference between two groups in a dataset.
Identify the appropriate statistical test in a dataset.
Competency 2: Analyze data using computer-based programming and software.
Performs appropriate statistical test of the difference between two groups in a dataset.
Competency 3: Interpret results of data analysis for value-based health care decisions, policy, or practice.
Interpret the results of a data analysis and state whether to accept or reject the null hypothesis based on the p-value and an alpha of .05.
Write a narrative summary of the results that includes practical, administration-related implications of the hypothesis test.
Competency 5: Communicate audience-appropriate health management content in a logically structured and concise manner, writing clearly with correct use of grammar, punctuation, spelling, and APA style.
Write clearly and concisely, using correct grammar, mechanics, and APA formatting.

Preparation
Download the Assessment 2 Dataset [XLSX].
The dataset contains the following variables:
clinic1 (total number of visits per month for clinic 1).
clinic2 (total number of visits per month for clinic 2).
Instructions
An investor needs to make a decision on whether to acquire one of two medical clinics based on their productivity, as measured by the total number of visits per month. You have been asked whether there is a significance difference in the total number of visits per month between clinic 1 and clinic 2.
For this assessment, perform hypothesis testing on the differences between two groups in the Assessment 2 Dataset. Create an appropriately labeled Excel document with your results. Also write an analysis of the results in a Word document. Insert the test results into this document (copied from the output file and pasted into a Word document). Refer to Copy From Excel to Another Office Program for instructions.
Submit both the Word document and the Excel file that shows the results.
