The author surveyed the students in one of his algebra classes, asking how many hours they spend watching TV shows, movies, and videos on a weekday. Here are their responses:

a. Is the observation 30 hours an outlier? What might the student have thought the question was? What type of bias is this? Because we cannot be sure what the observation means, remove it from the sample for parts (c) through (d).
b. One student wrote €œ4€“10.€ What value would represent this response well? Include the value in the sample for parts (c) through (d).
c. Construct a dotplot.
d. What proportion of the observations are between 2 and 4 hours, inclusive?
e. What proportion of the observations are less than 3 hours?
