Goal of this coding question:

1. illustrate descriptive graphics
2. how to display technical data
3. providing brief summarization of what was found

A patient takes the Bigomycin tablet. The tablet keeps disintegrating releasing the active ingredient of the drug into the bloodstream. Measure how much of the active ingredient of the drug is in the bloodstream of the patient over a 24-hour period. Then Cmax is the maximum of the ingredient of the tablet in the bloodstream. The Cmax values of 125 patients are given below.

Cmax <- c(739, 775, 765, 751, 761, 738, 759, 761, 764, 765, 749, 767, 764, 743, 739, 759, 752, 762, 730, 734, 759, 745, 743, 745, 751, 760, 768, 766, 756, 741,

1. What is the size of the data?
2. Obtain the summary statistics of the data.
3. What proportion of observations is between 745 and 761?
4. What percent of observations is between 741 and 765?
5. Obtain a frequency histogram of the data. The x- and y- axes should be spelled out. The main title should be enunciated. The vertical line at the median of the data should be etched. The median value should be printed on the x-axis. The word Median should be planted on the vertical line somewhere. A rug should be created under the histogram. Note down the width of each bar of the histogram.
6. Obtain a density histogram of the data. The x- and y- axes should be spelled out. The main title should be enunciated. The vertical line at the median of the data should be etched. The median value should be printed on the x-axis. The word Median should be planted on the vertical line somewhere. A rug should be created under the histogram. Note down the width of each bar of the histogram.
