1. Which of the following uses empirically derived formulas to predict effort as a function of LOC or FP?
a) FP-Based Estimation
b) Process-Based Estimation
c) COCOMO
d) Both FP-Based Estimation and COCOMO

Answer: d
Clarification: Function points and COCOMO are used to evaluate effort.

2. The empirical data that support most estimation models are derived from a vast sample of projects.
a) True
