Comparing language conversion rate (I)

The marketing team wants to determine how effective the campaign was on converting English speakers.

In this exercise, you will isolate the data for English speakers and calculate the conversion rate much like in the previous exercises. Remember, the formula for conversion rate is:

$$ \displaystyle\frac{\mbox{Number of people who convert}}{\mbox{Total number of people who we market to}} $$

Once you have the conversion rate for English speakers, you can compare it to the overall conversion rate to gain a sense of how effective the marketing campaign was among this group compared to the overall population.
