The following tables shows the hourly wages of all workers in a certain hospital. Determine the pearsonian coefficient of skewness (population data).

Hourly wages frequency
90-99 5
100-109 9
110-119 5
120-129 7
130-139 5
140-149 3

My answers:
mean = 116.56
s = 15.72
But i don't know how to solve for the mdn and the pearsonian coefficient of skewness. thank you:D
