5.11 Constructing a sampling distribution. Refer to Example 5.1 (page 283). Suppose Student Monitor also reported that the median number of hours per week spent on the Internet was 12.5 hours.
(a) Explain why we’d expect the population median to be less than the population mean in this setting by drawing the distribution of times spent on the Internet for all undergraduates. This is called the population distribution.
(b) Using Figure 5.2 (page 285) as a guide and your distribution from part (a), describe how to approximate the sampling distribution of the sample median in this setting.
