Using pseudocode, flowchart and C programming, construct statistics library as a header file called stats.h. Functions to include are:

- Mean

- Median

- Kurtosis

- Standard deviation

If your number is odd, check your library in a c program using the following data: Customer basket -> [22.3, 10.5, 60.5, 20.5, 22.5]

If your number is even, check your library in a c program using the following data: British Coins -> [1, 2, 5, 10, 20, 50]
