Does the size of a company’s IT department impact its cybersecurity incident rate? Let x represent the number of IT staff members, and let y represent the cybersecurity incident rate per year. Suppose a random sample of companies provided the following information. x 2 8 14 32 73 y 50 45 35 28 16 As x increases, does the value of r imply that y should tend to increase, decrease, or remain the same? Explain.
