Chapter 16.2, Problem 10E
In an experiment to study the way in which different anesthetics affected plasma epinephrine concentration, 10 dogs were selected and concentration was measured while they were under the influence of the anesthetics isoflurane and halothane (“Sympathoadrenal and Hemodynamic Effects of Isoflurane, Halothane, and Cyclopropane in Dogs” Anesthesiology [1974]: 465–470). The resulting data are as follows:

A study was conducted to examine the effect of diet cola consumption on calcium levels in women. A sample of 16 healthy women
aged 18 to 40 were randomly assigned to drink 24 ounces of either diet cola or water. Their urine was collected for three hours after
ingestion of the beverage and calcium excretion (in mg) was measured. The data are stored in ColaCalcium.
A study examined the impact of THC, the active ingredient in marijuana, on various physiological and psychological
variables. The study recruited a sample of 18 young adults who were habitual marijuana smokers. Participants came to the
lab 3 times, each time completing the entire series of tests and questionnaire, but each time smoking a different marijuana
cigarette: one with 3.9% THC, one with 1.8% THC, and one with no THC, a placebo. The order of the conditions was
randomized and participants were not told how much THC was in the cigarette they smoked until after all the data were
collected. This is an example of
a completely randomized experiment.

The fish were classified as piscivores (fish-eating), invertivores (invertibrateeating), omnivores (anything-eating) and algivores/detritivores (eating algae and other organic matter). For those fish in African waters, the data on theWeissStats site give the proportions of each species of fish with empty stomachs.
