In the context of the study described, the element of experimental design that is known to be a part of this study is **3) randomizing**.
Since the study involved selecting a sample of 1000 students, and assuming that this selection was done randomly (which is a common practice in such studies), it ensures that the sample is representative of the larger student population.
Blinding typically refers to concealing the treatment from participants or researchers, but this doesn't apply here as the study is measuring study hours, not a treatment. Replication usually refers to repeating an experiment or having enough participants to achieve reliable results, but in this question, it specifically highlights randomization as a crucial aspect of the design.
