The August 23, 1999, issue of the Tampa Tribune reported on a study involving data volunteered by 17,251 users of the abcnews. com website. Users of the site were asked to respond to questions including whether or not they used the Internet to escape problems, tried unsuccessfully to cut back their Internet use, and found themselves preoccupied with the Internet even when not using it. Almost 6% of those responding confessed to some sort of addiction to the Internet.
a. Identify the population and sample used in this study.
b. The number 6% applies to the sample and so is a statistic. Identify, in words, the corresponding parameter of interest in this study.
c. Do you think that 6% is a reasonable estimate of the parameter you defined in part b? If not, indicate whether you think this estimate is too high or too low. Explain.
