Old-fashioned mechanical alarm clocks were not very accurate about when the alarm went off. Suppose that the alarm on one
such clock is equally likely to go off at any time in the interval from 2 minutes before to 2 minutes after the time set for the
alarm to go off. Consider the distribution of the amount of time (in minutes) from when the alarm is set to go off to when it
actually goes off. Note that the value of this variable will be negative if the alarm goes off early.
(a) Draw a density curve that can be used to model this distribution. Be sure to include scales on both axes.
