A large online retailer places packed and ready-to-be-shipped boxes in a line on a conveyor belt. A sample of boxes will be used to estimate the mean weight of boxes shipped on a given day. One proposed method for selecting the sample is as follows: ⚫ Generate a random integer from 1 to 20. . Use that integer to select an initial box from the first 20 boxes in line on the conveyor belt. • Select every 25th box that follows the initial box on the conveyor belt for the rest of the day. Which of the following best describes the proposed sampling method? (A) Stratified random sample, stratified by time of day (B) Cluster sample, with times of day as clusters (C) Cluster sample, with box weights as clusters (D) Systematic random sample (E) Convenience sample
