- 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 (? = ?0) 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)

Introduction:
In this assignment, we will be working with the Gestation Demographics SEU dataset located in the Framingham dataset provided. We will be using R Studio or Excel to perform the following tasks: create a simple distribution graph (histogram) to explore the age of women after giving birth to their first child, determine the mean age of the women in the dataset, and test the hypothesis that the mean age for women giving birth is 37 years old.
1. Using the Gestation Demographics SEU dataset, 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.
2. Determine the mean age of the women in the Gestation Demographics SEU dataset.
3. We will be testing the hypothesis that the mean age for women giving birth is 37 years in the Gestation Demographics SEU dataset. The null hypothesis is that the mean age of women giving birth is 37 years old, and the alternative hypothesis is that the mean age of women giving birth is not 37 years old. We will be using our knowledge on hypothesis testing, specifically Chapter 7 on our text, to conduct this test.
