How does your web browser get a file from the Internet? Your computer sends a request for the file to a web server, and the web server sends back a response. For one particular web server, the time (in seconds) after the start of an hour at which a request is received can be modeled by a uniform distribution on the interval from 0 to 3600 seconds.

a. Draw a density curve to model the amount of time after an hour at which a request is received by the web server. Be sure to include scales on both axes.

b. About what proportion of requests are received within the first 5 minutes (300 seconds) after the hour?

c. Find the interquartile range of this distribution.
