Question

Delta Airlines quotes a flight time of 2 hours, 3 minutes for a particular flight. Suppose we believe that actual flight times are uniformly distributed between 2 hours and 2 hours, 12 minutes.

(a)

Show the graph of the probability density function for flight time.

The graph has a shaded area. The horizontal axis is labeled: x with the title: Flight Time in Minutes and has tickmarks labeled: 114, 120, 126, 132. The vertical axis is labeled: f(x), and has tickmarks labeled: 1/12, 1/6, 1/4. The shaded area is the region bounded by the horizontal axis and the following line segments.

A 1/12 unit long vertical line segment begins at 120 on the horizontal axis.
A 1/12 unit long vertical line segment begins at 126 on the horizontal axis.
A 6 unit long horizontal line segment begins at the tickmark labeled 120 on the horizontal axis and the tickmark labeled 1/12 on the vertical axis. This line segment connects the two vertical line segments.

A 1/12 unit long vertical line segment begins at 114 on the horizontal axis.
A 1/12 unit long vertical line segment begins at 126 on the horizontal axis.
A 12 unit long horizontal line segment begins at the tickmark labeled 114 on the horizontal axis and the tickmark labeled 1/12 on the vertical axis. This line segment connects the two vertical line segments.

A 1/12 unit long vertical line segment begins at 120 on the horizontal axis.
A 1/12 unit long vertical line segment begins at 132 on the horizontal axis.
A 12 unit long horizontal line segment begins at the tickmark labeled 120 on the horizontal axis and the tickmark labeled 1/12 on the vertical axis. This line segment connects the two vertical line segments.

A 1/12 unit long vertical line segment begins at 114 on the horizontal axis.
A 1/12 unit long vertical line segment begins at 132 on the horizontal axis.
A 18 unit long horizontal line segment begins at the tickmark labeled 114 on the horizontal axis and the tickmark labeled 1/12 on the vertical axis. This line segment connects the two vertical line segments.

(b)

What is the probability that the flight will be no more than 3 minutes late?

(c)

What is the probability that the flight will be more than 6 minutes late?

(d)

What is the expected flight time, in minutes?
