Butz et al. evaluated the duration of benefit derived from the use of noninvasive positive-pressure ventilation by patients with amyotrophic lateral sclerosis (ALS) on symptoms, quality of life and survival. ALS, aka Lou Gehrig's Disease, is a degenerative disease of the motor neurons. One of the variables of interest is partial pressure of arterial carbon dioxide (PaCO2). The values below (measured in mm Hg) reflect the results of baseline testing on 20 of the 30 subjects in the study, as established by arterial blood gas analyses. (Am. J Med.

Hint: To create a histogram, you would first need to decide on the bin ranges. Since the data is numerical and ratio,…
The aging Neotropical termites (Neocapritermes taracua) secrete a sticky, blue-colored liquid that they spew to intruding termites. The younger Neotropical termites secrete a liquid that lacks the blue component, so it is white in appearance. In an experiment that measured the toxicity of the blue substance, the researchers placed one drop of either the blue liquid or the white liquid on individuals of a second termite species, Labiotermes labralis. Of the 41 Labiotermes labralis that got the blue drop, 37 were immobilized. Of the 40 Labiotermes labralis that got the white drop, 9 were immobilized. Is the blue liquid toxic compared to the white liquid?
