Answer 1

C. Starting salaries

Explanation:

The random variable is the variable that is being descripted by the distribution. In this case, it is the variable "Starting salaries of individuals with an MBA degree".

It can take any values, but its probability is defined by the distribution and its parameter (mean and standard deviation). In theory, it could take negative values, but they would not have any validity in the real world.
