CHEGG. The U. S. National Toxicology Program (NTP) studied the toxicity and carcinogenicity of agents potentially causing a risk to human health. Electromagnetic fields around electrical installations are harmless in theory, but they might have a long‑term effect on health (for instance, in triggering tumors). Observational studies in human populations have suggested a potential association. An NTP study looked at the occurrence of cancers in otherwise healthy rats after two years of daily exposure to 60 ‑hertz electromagnetic fields of various intensities. The numbers of male and female rats with a tumor after the two‑year study period is displayed. Note that 2 Gauss is approximately 1000 ‑fold greater than what is considered high exposure for humans. Male rats Female rats
Control: no exposure 16 ( n=99 ) 19 ( n=100 )
0.02-gauss exposure 31 (n = 100) 22 (n = 100)
2-gauss exposure 30 (n = 100) 22 (n = 100)
In rats not exposed to an electromagnetic field (sample size in parentheses), is there significant evidence of a difference in the tumor rates between males and females?

You are chairman of the board of a successful technology firm. there is a nominal federal corporate tax rate of 35 percent, yet the effective tax rate of the typical corporation is about 12.6%. your firm has been clever with use of transfer pricing and keeping money abroad and has barely paid any taxes over the last 5 years; during this same time period, profits were $28 billion. one member of the board feels that it is un-american to use various accounting strategies in order to avoid paying taxes. others feel that these are legal loopholes and corporations have a fiduciary responsibility to minimize taxes. one board member quoted what the ceo of exxon once said: “i’m not a u.s. company and i don’t make decisions based on what’s good for the u.s.” what are the alternatives? what are your recommendations? why do you recommend this course of action?
