Suppose you use Google Analytics to optimize your online adds. You run two different ads, ad A and ad B, for a month. How should you go about making decisions regarding the results? Use statistical hypothesis testing with p=0.05 to decide if there is a statistically significant difference in the click rate of the two. Determine what metrics (click rate, sales, net profit, etc) to use for evaluation and hypothesis testing to determine if there is a statistical significant difference between the ad A and ad B result, with respect to the metrics and determine if this difference is practically significant. Compare the click rates of ad A and ad B and chose the ad with the higher click rate for future campaigns
