A statistics instructor at SUSS is conducting a study to find out if spacing out assignment deadlines affects students' performance on their assignments. She set both of her tutorial groups three assignments. However, she randomly assigned one tutorial group (n = 9) to have separate deadlines: Week 3 for the first assignment, Week 6 for the second assignment, and Week 8 for the third assignment. The second tutorial group (n -9) had a single deadline: Week 8 for all three assignments. The instructor graded all the assignments at the end of the semester, taking care to anonymize the assignments first. The total marks for the three assignments (marked out of a maximum of 30 marks) are in the table below.

She placed the same orders from 5 different restaurants via both Deliveree and FoodMonkey and recorded the amount of time each delivery service took to deliver her orders. Her data are presented in the table below: Time Taken to Deliver Order (Minutes) Restaurant Food Ordered Deliveree FoodMonkey Chicken Rice 60 65 Pizza 120 130 Sushi 60 70 Nasi Lemak 35 Curry Rice 90 75
