An organization conducts an annual survey of cybersecurity at firms from around the world. In a recent year, the organization sent survey questionnaires via email to all professionals that hold a certified nformation security manager designation. Of the 1,401 firms that responded to the survey, 1,107 (or 79 %) expect to experience a cyberattack (for example, aMalware, hacking, or phishing attack) during the year. You are to estimate the probability of an expected cyberattack at a firm during the year with a 95% confidence interval. Answer the followings: a. 5. ». 1. What is/are the critical value(s)? What is the margin of error? Identify the 95% confidence interval for the probability of an expected cyberattack at a firm during the year. If the margin of error should be 0.02 or less, what would be the minimum sample size?
