A hospital researcher has found that the mean length of time that patients stay in the hospital is 4.9 days with a standard deviation of 3.5 days.(adsbygoogle = window.adsbygoogle || []).push({});

a) Using just the information on the mean and standard deviation, justify why the length of stay would NOT be normally distributed.Would the length of stay be positively skewed or negatively skewed?

So, what is the mode or median for this? Because I need to use the Pearson's formulas and we need to know either the mode/median.

Skewness = (mean - mode / standard deviation)

Skewness = 3(mean - median / standard deviation)

Skewness = [tex]\frac{\bar{x} - mode}{s}[/tex] or

[tex]\frac{3(\bar{x} - median)}{s}[/tex]
