Question

The lengths of stay of 20 patients hospitalized with a digestive dis- order are as follows: 10, 4, 5, 8, 5, 7, 9, 11, 4, 3, 6, 9, 8, 5, 13, 4, 6, 8, 9, 3 Similarly, the lengths of stay of 15 patients hospitalized with coro- nary heart disease are as follows: 11, 13, 16, 12, 5, 8, 9, 5, 6, 7, 4, 8, 9, 7, 8

Use Excel to find the mean, the mode, the median, the standard deviation, the range, and the co- efficient of skewness for both sets of data.

In addition, use Excel to find the 1st quartile, the 3rd decile, and the 40th percentile.
