Create a simple distribution graph (histogram) where we will explore the age of women after giving birth to their first child. Remember that a histogram consists of parallel vertical bars that show the frequency distribution of a quantitative variable in the graph.

Summarizing Data Collected in a Defined Population Sample (Biostatistics)

Critical Thinking Assignment

This week we are learning about ordinal/categorical, continuous, and dichotomous variables. Using the Gestation Demographics SEU dataset that is located in the tabs at the bottom of the Framingham dataset provided, perform the following problems using R Studio or Excel.

• Create a simple distribution graph (histogram) where we will explore the age of women after giving birth to their first child. Remember that a histogram consists of parallel vertical bars that show the frequency distribution of a quantitative variable in the graph. See the example in Introductory Statistics with R on pages 71-7 or pages 123-124 in EXCEL statistics A quick guide. The area of each bar is equal to the frequency of items found in each class.
• Determine the mean age of the women in the Gestation Demographics SEU dataset.
• We will be testing the hypothesis that the mean age (μ = μ0) for women is 37 years in the Gestation Demographics SEU dataset. The topic of hypothesis testing was introduced in HCM505. If you need a review see Chapter 7 of our text.

H₀ The mean age of women giving birth is 37 years old. (Null Hypothesis)
H₁ The mean age of women giving birth is not 37 years old. (Alternative Hypothesis)

Ensure to submit the following requirements for the assignment:

• Present your findings in a Word document, by copying and pasting the histogram into the document.
• After your analysis state whether you accept or reject the null hypothesis and your reasoning why.
• Always use a title page, an introduction, a discussion where you interpret the meaning of the histogram, and a conclusion should be included.
• Your submission should be 3 pages to discuss and display your findings.
• Provide support for your statements with in-text citations from a minimum of three scholarly, peer-reviewed articles. One of these sources may be from the class readings, textbook, or lectures, but the others must be external. The Saudi Digital Library is a good place to find these sources and should be your primary resource for conducting research.
• Follow APA 7th edition and Saudi Electronic University writing standards.
