A certain assembly project requires the completion of each of 5 tasks. In the diagram, the tasks are represented by circles labeled A–E and the number above each circle represents the number of days needed to complete the task. Arrows indicate prerequisite tasks. For instance, the arrow from Task A to Task C indicates that Task A must be completed before Task C can be started. Unless otherwise prohibited by these constraints, several tasks can be worked on at the same time. The project is complete once all 5 tasks are completed. Use the drop-down menus to create the most accurate statements based on the information provided.  4A
The least number of days needed to complete the project is days. 4B If the number of days needed to complete Task C is increased by 1 day, then the least number of days needed to complete the project

 The graph shows data for 40 children, half of whom were male (M) and half of whom were female (F), in each of three age groups: at least 9 but less than 10 years old, at least 11 but less than 12 years old, and at least 13 but less than 14 years old. These children were taught to perform chest compressions used in cardiopulmonary resuscitation (CPR). For CPR, ideal compression depth is 40 to 50 millimeters (mm). The children used a practice mannequin with sensors that recorded the average (arithmetic mean) depth achieved by each child. The results are plotted on the graph. Based on the information provided, select from each drop-down menu the option that completes the statement most accurately. 8A In the study, age and average compression depth are positively correlated for
8B Among the three age groups displayed, the median average compression depth is in the ideal range for CPR for the group of children who are at least years old.
