Below are EMG traces from bipolar surface electrodes placed on four muscles, recorded at once. The trace at the bottom is the force, which shows that the subject increased force almost immediately, and maintained a target level of force production for several minutes. The force trace was recorded by a force-measuring device placed beneath a foot pedal; so, pressing down on the pedal with the foot produced the change in force shown on the bottom. Based on this information, which of the EMG traces below corresponds to the agonist muscle producing the force?

Reseаrchers wаnted tо study the hаnd washing behaviоr оf nursing students completing clinical rotations in their hospital. They compiled a list of all schools with nursing students who complete clinical rotations in the hospital and randomly selected two of the schools. All nursing students from the selected schools were observed during clinical rotations for a period of two years. During the observations, the frequency of hand washing (number of times per shift) for each student was recorded along with the length of time spent hand washing (in seconds), and the reason for hand washing (start of shift, preparing to draw blood, etc.). What type of sampling was used?
