Use an Existing Data Set to Develop a Research Question, Hypothesis, and Histogram
A pharmaceutical company has approved a new medication to help with depression symptoms, and they need your help! 

Assignment Instructions: Please use the Week 3 Assignment Template to complete this assignment. You can download the template from the Libguide/ Course Resources section.

Part 1: The pharmaceutical company is trying to figure out if the new medication significantly decreases depression symptoms. Please complete the following:

Write a research question that applies to what the company is requesting.
Write a corresponding null hypothesis for the research question.
Write a corresponding alternative hypothesis for the research question.
State the alpha level that you would use for an analysis and what the results would mean if the significance level was above or below that value.
Discuss why hypothesis testing is important (use at least one resource to support your answer).
Part 2: 

Define statistical assumptions and define normality (use at least two resources to support your answer).
Using the Week3_DataSet.sav data set, assess the normality of the Medication variable and the No_Medication variable. There are many ways to assess normality, but you will only use two: the Shapiro-Wilk test and histogram visualization. You will follow the instructions in the Verma and Abdel-Salam (2019) reading. First, assess normality using the Shapiro-Wilk test. You will create two SPSS outputs for this test, one for each of the variables.
For each SPSS output of the Shapiro-Wilk test, state whether normality was or was not met, including the p value.
Next, create two histograms, one for the Medication variable and one for the No_Medication variable. The histograms will be generated in the SPSS output area. Please take a screenshot of the histograms and insert them into your Word document used for Part 1 of this assignment. 
For each histogram, please state whether the data appear to be normally distributed based on your visual interpretation of the histogram. Please write a brief summary (2-3 sentences) based on your findings. 
For each histogram, you can see the Mean and Standard Deviation in the top right-hand corner of the histogram. Based on this information alone, would you predict that the medication helped decrease depression symptoms? Hint: you will be comparing the means of the two histograms; note that higher scores indicate the presence of more depression symptoms.
In 2-3 sentences discuss whether the results were the same for both the Shapiro-Wilk test and your visual interpretation of the histograms.
Length: 45 pages (in addition to title page and references) 

References: Include a minimum of 3 scholarly resources
