Given the altitude of lakes in feet: –12, –9, –14, –39, –49, –49, –18, –43, find the mean, median, mode, and range.

(1 point)

mean = –28.5, median = –29.1, mode = –49, range = 40

mean = –29.1, median = –49, mode = –28.5, range = 41

mean = –49, median = –29.1, mode = –28.5, range = 41

mean = –29.1, median = –28.5, mode = –49, range = 40
