When you put the earthworm farmers' salaries in numerical order to find the mean ($10,000, $18,000, $18,000, $19,000, $19,000, $19,000, $20,000, $20,000, $45,000), you discover that it is $19,000. That is more in line with what the majority of earthworm farmers in our example earn than the average or mean of $20,889.
The months November, December, January, Feburary, March and April are considered the months when the flu virus is most active. At this time you may experience symptoms like cold, chills, runny nose and congestion.
Germs generally remain active longer on stainless steel, plastic and similar hard surfaces than on fabric and other soft surfaces. Other factors, such as the amount of virus deposited on a surface and the temperature and humidity of the environment, also determine how long cold and flu germs stay active outside the body. It's possible to catch the flu or a cold after handling an object an infected person sneezed or coughed on a few moments ago.
