Question

Hello,

Please help to put the arguments into standard form for inductive generalizations (sampling arguments) and evaluate the strength.

1. An investigator studied several thousand heroin users and learned that 70 percent of them had used marijuana before they tried IV. Arguments Based on Samples 155 heroin. He concludes that roughly 70 percent of all marijuana us ers will go on to try heroin.

2.  At the University of Pennsylvania, psychiatrists conducted a study to determine the social factors that affect the well-being of coronary patients. There we re ninety-three patien ts in the study; slightly more than 50 percent of th em had pets of some kind (dogs, cats, fish, and one iguana). At the end of a year, one-third of the patients who did not own pets had died, but only three animal ow ners had succumbed. The psychiatrists concluded that pet ownership may have a positive effect on the health of humans.
