Are these data homogeneous or heterogeneous? Why? What do these data tell you about wellness at your corporation? Remember that 200 is the cut-off for overall cholesterol levels (lower is better).

Answer 1

solution:

for given data

n=60

sum of all number =12206

mean=203.433

median=189

mode=188(repeated number)

range=188

minimum=139

maximum=327

variance=2040.91166

standard deviation=45.17645

this is  homogeneous population (all items in the population have the same characteristics).where as heterogeneous population (all items in the population have different characteristics) heterogenous population example is sample of 18-21 year old students in history 112, chemistry 211 and physics 101
