The u. s. national toxicology program (ntp) studies 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. here are the numbers of male and female rats with a tumor after the two-year study period. note that 2 gauss is approximately 1000-fold greater than what is considered high exposure for humans. male rats female ratscontrol: 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? h0: pmale = pfemaleha: pmale ≠ pfemalei have figured out the null but not sure how to go about getting the χ exsplain than you. what is the value of the test statistic?
