The time required to cure concrete is pivotal in the construction business.Insufficient curing time results in lower structural strength,which can create hazardous design conditions.Too much time wastes valuable resources and may result in greatly inflated building costs.To help ascertain the optimum curing time,a random sample of 80 poured concrete foundations is drawn.The total time to completely cure each foundation is recorded.This study is BEST described as a(n)_____ study.
A) observational
B) longitudinal
C) experimental
D) inferential

Question
