Where’s the bus? Sally takes the same bus to work every morning. The amount of time (in minutes) that she has to wait for the bus can be modeled by a uniform distribution on the interval from 0 minutes to 10 minutes.

a. Draw a density curve to model the amount of time that Sally has to wait for the bus. Be sure to include scales on both axes.

b. On about what percent of days does Sally wait between 2.5 and 5.3 minutes for the bus?

c. Find the 70th percentile of Sally’s wait times.
