An article in Proceeding of the 33rd International ACM SIGIR Conference on Research and Development in Information Retrieval [\"Understanding Web Browsing Behaviors Through Weibull Analysis of Dwell Time\" (2010, p.379-386)] proposed that a Weibull distribution can be used to model Web page dwell time (the length of time a Web visitor spends on a Web page). For a specific Web page, the shape and scale parameters are 1 and 300 seconds, respectively. Determine the following: Mean and variance of dwell time. Probability that a Web user spends more than four minutes on this Web page. Dwell time exceeded with probability 0.25.
