Most American households have one digital video recorder (DVR), and many have more than one. A sample of 25 households produced the following measurements of x, the number of DVRs in the household.

1	0	2	1	1
1	0	2	1	0
0	1	2	3	3
1	1	1	0	1
3	1	0	1	1

Is the distribution of x, the number of DVRs in a household, symmetric or skewed? Explain.

Guess the value of the mode, the value of x that occurs most frequently.

Calculate the mean, median, and mode for these measurements.

Draw a relative frequency histogram for the data set.

Locate the mean, median, and mode along the horizontal axis. Are your answers to parts (a) and (b) correct?
