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?

What are the forecasted levels of the line of credit and special dividends? (hints: create a column showing the ratios for the current year; then create a new column showing the ratios used in the forecast. also, create a preliminary forecast that doesn’t include any new line of credit or special dividends. identify the financing deficit or surplus in this preliminary forecast and then add a new column that shows the final forecast that includes any new line of credit or special dividend.) now assume that the growth in sales is only 3%. what are the forecasted levels of the line of credit and special dividends?
