By 1984, there were only 44,250 fatalities, but that is still far too many. The reductions between 1965 and 1984 were due primarily to federal requirements for motor vehicle safety. So, even stricter federal safety controls should be required.

Analyze the following study according to the criteria set by your instructor:
"Barbara Sherwin, director of a research team at McGill University, found that a small quantity of the male hormone testosterone, in addition to estrogen, led to a spicier sex life for some postmenopausal women. Twenty-two of the McGill teams subjects were given 150 milligrams a month of testosterone with estrogen, 11 were given estrogen alone, and 11 took placebos. The testosterone group reported more desire and arousal and more frequent sexual thoughts than did the women in the other two groups. Though 17 percent of the testosterone recipients developed mild facial hair, this side effect receded when the dosage was reduced."

The researchers monitored the daily hormone levels in 28 college women who did not exercise regularly and had a history of regular menstrual cycles. The women were then sent to summer camp and participated in a rigorous exercise programan initial 4-mile daily run, working up to 10 miles a day after five weeks, in addition to three and one-half hours daily of moderate sports such as biking or tennis. Only four, three of whom were on a high-calorie weight maintenance diet, had a normal menstrual cycle during that time. The researchers concluded that, regardless of whether the women lost weight, strenuous exercise disrupted their reproductive function. If very active women are having trouble getting pregnant, they probably should slow down intense exercise, says exercise physiologist Gary Skrinar of BU."Science News

Paul Tullius kept records for over a year about his cholesterol levels and his intake of fats and carbohydrates. He found that his cholesterol levels seemed to be influenced very little by the amount of fat he ate, but varied directly with his consumption of carbohydrates. The more of the latter he ate, the higher his cholesterol went. Conversely, when he cut back on the carbs, his cholesterol level dropped back below his usual numbers. He concluded that it was carbs that caused his cholesterol levels to be so high for several years.

To determine what the residents of the town thought about this annexation and about municipal growth in general, the city council had a poll taken. One thousand of the citys fifteen thousand registered voters were randomly selected and asked three questions: (1) Do you favor no growth, modest growth, or accelerated growth for Hamilton City? (2) Do you favor annexation of the eight-hundred-acre Osborne parcel north of town and its planned subdivision? (3) Should the city enter into agreements with developers promising to supply city services, such as sewers and street maintenance, in return for the added tax revenue the developers projects will produce? The results of this survey were taken to be the "official" opinion of the voters of Hamilton City.
