Part A (Introduction): a) Write an introduction: . Explain the problem in general (e.g., vitamin D deficiency and recommended vitamin D level). Support your opinion with at least one reference (Harvard referencing), and • Introduce all 5 variables: country (add frequency table), sun exposure (add frequency table), gender (add frequency table), age (add summary statistics vs. country, sun exposure and gender), and vitamin D level (add summary statistics vs. country, sun exposure and gender). Plot a histogram with a superimposed normal curve for both age and vitamin D level and describe your findings. Convert age to a categorical variable (call it NewAge) with 2 levels (<40= "1", ≥ 40 "11") Create a side-by-side boxplot for vitamin D level vs. NewAge and a side- by-side boxplot for vitamin D level vs. country. Create a scatterplot to show the relationship between vitamin D level and Age. Compare these two side-by-side boxplots and the scatterplot and explain your findings. Note: Write appropriate captions for the tables, graphs, and outputs.

Transcribed Image Text:Part A (Introduction):
a) Write an introduction:
.
Explain the problem in general (e.g., vitamin D deficiency and
recommended vitamin D level). Support your opinion with at least one
reference (Harvard referencing), and
• Introduce all 5 variables: country (add frequency table), sun exposure
(add frequency table), gender (add frequency table), age (add summary
statistics vs. country, sun exposure and gender), and vitamin D level (add
summary statistics vs. country, sun exposure and gender).
Plot a histogram with a superimposed normal curve for both age and
vitamin D level and describe your findings.
Convert age to a categorical variable (call it NewAge) with 2 levels
(<40= "1", ≥ 40 "11")
Create a side-by-side boxplot for vitamin D level vs. NewAge and a side-
by-side boxplot for vitamin D level vs. country.
Create a scatterplot to show the relationship between vitamin D level
and Age.
Compare these two side-by-side boxplots and the scatterplot and explain
your findings.
Note: Write appropriate captions for the tables, graphs, and outputs.
