Imagine that you work in web media, and your company publishes news and analysis. Success is measured by the amount of time visitors stay on the site consuming content (longer time is better). Two websites are created and tested: Deep-Analysis (DA) vs. Just-Headlines (JH). An analysis of the duration of time spent by unique visitors is as follows: DeepAnalysis: 1000 unique Visitors; Duration= 2:40 (hh:mm); std.deyiation = 25 minutes. (or in decimal numbers, mean=2.66, sd=0.42) Just-Headlines: 1000 unique visitors; Duration: 2:15 (hh:mm); std.deviation =30 minutes. (or in decimal numbers, 5L3 mean=2.25, sd=0.50) Test the null hypothesis claim at 00% condence (or alpha=.10} that the difference in time spent between these two sites is not signicantly different from zero. (i.e. Note that this means that the null hypothesis is claiming that the same amount of time is spent on these sites). Do you retain or reject the null hypothesis
