📝 Answered - Consider the following application exercise from page 198 of the prescribed textbook. Advertisers contract with internet service providers and search engines to place ads on their website. They pay a fee based on the number of potential customers who click on their ad; unfortunately, click fraud has become a problem. 40% of advertisers claim to have been a victim of click fraud (assume this to be the population proportion).
