2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

Your favorite soccer player is playing in the world cup and the match has ended in a tie. As the teams get ready for the penalty shootout, you know your favorite player will be last to shoot. A quick search tells you that your favorite player makes a goal when kicking from the penalty mark 0.80% of the time. You also know that the player before your favorite player makes a kick from the penalty mark 0.60% of the time. What is the probability that only one goal is scored between both players? Report your answer to the second decimal point, that is, 0.45 instead of 0.5.
