Malicious Android smartphone apps use reflection application program interfaces (APIs) to access user data and steal personal information while evading detection. A paper published in Computers & Security (March, 2020) proposed a new, fast, and efficient tool for detecting a malicious reflection API on Android apps. Initially, the researchers investigated the degree to which Android apps are attacked by the malware. For a sample of 660 Android apps, they found 267 with a malicious reflection API. Use the methodology of this section to provide the researchers with an estimate of the true proportion of Android apps with a malicious reflection API. What is your measure of reliability for the estimate? Give a practical interpretation of the result.
