Answer:
False
Explanation:
All of the statements being made are False. Productivity is measured by stats. For example, in any given month a certain number of products are produced by a fixed number of employees, the next month the same value is calculated and compared with the previous month. This lets you know if productivity is increasing or decreasing. The quality of anything depends on the time and effort being implemented in making something, if this changes then so does the quality. Exogenous variables are simply variables that are not affected by other variables in a given environment, this does not mean that they cannot change. Even though they are independent they can still change. For example, the weather is an exogenous variable but it can still change from Raining to Sunny.
