A question in the 2002 General Social Survey (GSS) conducted by the National Opinion Research Center asked participants how long they spend on e-mail each week. A summary of responses (hours) for n = 1881 respondents follows. (The data are in the dataset GSS-02 on the companion website.)

Mean	StdDev	Minimum	Q1	Median	Q3	Maximum
4.14	7.235	0	0	2	5	70

a. Explain how the summary statistics show us that at least 25% of the respondents said that they do not use e-mail.

b. What is the interval that contains the lower 50% of the responses?

c. What is the interval that contains the upper 50% of the responses?

d. Explain whether or not the maximum value, 70 hours, would be marked as an outlier on a boxplot.

e. Calculate Range/6 and compare the answer to the value of the standard deviation. What feature(s) of the data do you think causes the values to differ?
