.. ... Catapult A 125 130 135 140 145 150 155 Catapult B 125 130 135 140 145 150 155 Distance (in centimeters) The plot above shows how far two catapults launched a bean bag over 40 trials. What is the third quartile (Q3) for catapult A? Suppose you worked as Assistant to the Regional Manager at a small regional paper company. You want to check that the warehouse workers are correctly filling orders. Since you cannot check every order and perform your regular job duties, you decide you will take a sample of 20 shipments from the 200 orders for the week. Which of the following correctly describes a stratified random sample? Since multiple shipments end up on a single truck, randomly select 2 truckloads to inspect all shipments on. Since there are 4 warehouse employees who sign off on the shipments, you randomly select 4 shipments packed by each of the 5 employees. O Using a random number generator, select 20 numbers (without replacement) from 1-200, and then select those shipments from the list of orders to check. Since the warehouse workers are more likely to be tired and make mistakes at the end of the week, wait and check the last 20 shipments leaving the warehouse. O After choosing a random starting point, choose every 10th shipment from the list of orders to check. Next
