A$/$B testing allows businesses to test a new design or format for a web page to determine if the new web page is more effective than the current one. Web designers decide to create a new$$ call$-$to$-$action button for a web page. Every visitor to the web page was randomly shown either the original$$ call$-$to$-$action button$($the control$)$ or the new variation. The metric used to measure success was the download$$ rate: the number of people who downloaded the file divided by the number of people who saw that particular$$ call$-$to$-$action button. Results of the experiment yielded the data in the first accompanying table. Use the information and data provided in the accompanying tables to complete$($a$)$ through$($j$).$
