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")
