Lesson 2.3 - Density Curves and the Normal Distribution Quick Notes Lesson App 2.3 Still waiting for the server? 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 randomly selected request is received can be modeled by a uniform distribution on the interval from 0 to 3600 seconds. 1. 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. 2. About what proportion of requests are received within the first 5 minutes (300 seconds) after the hour? 3. Find the interquartile range of this distribution. 4. What is the mean of the density curve? Explain your answer. 5. What is the median of the density curve? Explain your answer. STATS MEDIC
