Auser calls to report that she’s unable to log on to e-mail, and you ask a couple of questions. because you know that no one else is using the network right now, you can’t determine whether the problem is unique to her machine or affects the entire network. probing further, you learn that she’s also unable to print. you decide this problem is probably easier to troubleshoot from the user’s computer. using the eight-step problem-solving process covered in this chapter, outline the items you must check and the questions you must ask when you arrive at the user’s office. based on the possible responses to your questions, describe the actions you will take to correct potential causes of this problem.

Explain the circumstances for which the interquartile range is the preferred measure of dispersion. what is an advantage that the standard deviation has over the interquartile range? choose the correct answer below. a. the interquartile range is preferred when the distribution is symmetric. an advantage of the standard deviation is that it increases as the dispersion of the data increases. b. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation. c. the interquartile range is preferred when the distribution is symmetric. an advantage of the standard deviation is that it is resistant to extreme values. d. the interquartile range is preferred when the data are bell shaped. an advantage of the standard deviation is that it is resistant to extreme values. e. the interquartile range is preferred when the data are skewed or have outliers. an advantage of the standard deviation is that it uses all the observations in its computation. f. the interquartile range is preferred when the data are bell shaped. an advantage of the standard deviation is that it increases as the dispersion of the data increases.
