Matched Pairs: Kicking a hellium-filled foot- ball 1 Does a football filled with helium travel farther than one filled with ordinary air? To test this, the Columbus Dispatch conducted a study. Two identical footballs, one filled with helium and one filled with ordinary air, were used. A casual observer was unable to detect a difference in the two footballs. A novice kicker was used to punt the footballs. A trial consisted of kicking both footballs in a random order. The...

3. A sports writer wished to see if a football filled with helium travels farther, on average, than a football filled with air. To test this, the writer used 18 adult male volunteers. These volunteers were randomly divided into two groups of nine men each. Group 1 kicked a football filled with helium to the recommended pressure. Group 2 kicked a football filled with air to the recommended pressure. The mean vardage for Group 1 was "=300 yards with a...

An experiment is conducted in order to determine how different dosages of Vitamin D affect bone mineral density in individuals over the age of 70 years. Researchers are able to recruit 379 volunteers over the age of 70 to participate in the experiment. Each individual is randomly assigned to be given one of three doses of Vitamin D—either 300, 600, or 1200 micrograms—once a month over the course of one year. At the start of the experiment, bone mineral density...

Can Dogs Understand Human Cues? EXPLORATION Dogs have been domesticated for about 14,000 years. In that time, have they been able to develop an understanding of human gestures such as pointing or glancing? How about simi lar nonhuman cues? Researchers Udell, Giglio, and Wynne tested a small number of dogs in order to answer these questions. In this exploration, we wll first see whether dogs can understand human gestures as well as nonhuman gestures. To test this, the researchers positioned...

1. In the regression equation, the value that gives the amount by which Y changes for one unit in X is called the (a) coefficient of correlation. (b) coefficient of determination. (c) slope. (d) intercept. 2. For any two categorical variables, X and Y, the best way to determine if they are related is to (a) calculate the correlation between X and Y. (b) draw a scatterplot of the X and Y values. (c) make a two-way table of the...

Article Summary: Through the act of touching someone, we communicate a variety of intentions, ranging from love or sexual desire to dominance or aggression. The authors of the study review results of previous research on interpersonal touch, showing, for example, that an innocuous touch of another person can have positive effects, such as increasing ratings of liking a person. There also appear to be differences both in the way that males and females touch one another and in how they...
