3. For the studies described, identify the population, sample, population parameters, and sample statistics: a) In a USA Today Internet poll, readers responded voluntarily to the question "Do you consume at least one caffeinated beverage every day?" b) Astronomers typically determine the distance to galaxy (a galaxy is a huge collection of billions of stars) by measuring the distances to just a few stars within it and taking the mean (average) of these distance measurements.

answer  questions B) C) D in detail.

Consider these sample data: x, = 15, x2 = 9, x3 = 8, X4 = 19. a. Find n. b. Compute Ex. c. Determine x.

equal to: A. 8 В. 10 C. 6400 D. 4096 9L When calculating the median for a dataset consisting of an even number of scores (i.e. 2,4,6 etc.) which of the following is correct? A Calculate the average value of the three middle ranked scores A Calculate the mean for the whole dataset which would provide the same answer C. Calculate the average value of the two middle ranked scores D. Calculate the mode and use instead 10. Which of the following statements concerning the mean is incorrect? A. The mean is sensitive to a single extreme value B. The mean is a more complex descriptive statistic than either the mode or median C. The mean should always be used as the preferred measure to indicate a typical score D. The mean provides the most sensible result when the interval/ratio dataset has a symmetrical set of scores 11. Which of the following statements is the most accurate description for the concept of standard deviation? A. The square root of the total distance from the smallest score to…
