Problem 19E
According to the Environmental Protection Agency, chloroform, which in its gaseous form is suspected to be a cancer-causing agent, is present in small quantities in all the country’s 240,000 public water sources. If the mean and standard deviation of the amounts of chloroform present in water sources are 34 and 53 micrograms per liter (μg/L), respectively, explain why chloroform amounts do not have a normal distribution.
ANSWER:
Step 1 of 2:
It is given that chloroform is suspected to be the cancer causing agent by Environmental Protection Agency.
Also,the mean of the amounts of chloroform present in 2,40,000 public water sources is 34(mg/L) and standard deviation of amounts of chloroform is 53 micrograms per litre.
Using these we have to explain why chloroform amounts do not follow normal distribution.
