Module 09: Critical Thinking

Critical Thinking Assignment (105 points)

Using the Gestation Demographics SEU dataset provided (file located at the bottom of this screen), perform the following problems using RStudio.

1. 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 71-72. The area of each bar is equal to the frequency of items found in each class.

2. Determine the mean of the age of the women in the Gestation Demographics SEU dataset.

3. Test the hypothesis that the mean age (μ = μ0) for women is 37 years in the Gestation Demographics SEU dataset.

Print your plots to PDF or take screenshots and include with your submission. Present your findings in a Word document, with a title page included. Your submission should be as many pages as you need to display your findings.
