A researcher was administering a simple reaction time test to one of his study participants. They were instructed to push a button as soon as they heard a high-pitch tone. Figure 1 represents an EMG signal of a flexor muscle of the index finger (high amplitude indicates a button press). Based on this signal below, which segment of the EMG signal represents the time it took to process the auditory stimulus the participant heard: 1023 5 1 2 600 400 200 0 Segment 1 Segment 5 Segment 2 Segment 4 3 4

Researchers at the University of Mississippi wanted to learn the reaction times of students to different stimuli. In the data that follow, the reaction times for subjects were measured after they received a simple stimulus and a go/no-go stimulus. The simple stimulus was an auditory cue, and the time from when the cue was given to when the student reacted was measured. The go/no-go stimulus required the student to respond to a particular stimulus and not respond to other stimuli. Again, the reaction time was measured. The following data were obtained:The researchers used MINITAB to test whether the simple stimulus had a lower reaction time than the go/no-go stimulus. The results of the analysis are as follows: (a) State the null and alternative hypotheses. (b) Is the median reaction time for the go/no-go stimulus higher than the median reaction time for the simple stimulus? Use the $\alpha=0.05$ level of significance. Why? (TABLE CAN'T COPY)

Inferences about the Difference between Two Medians: Independent Samples
Reaction Time In an experiment conducted online at the University of Mississippi, participants are asked to react to a stimulus such as pressing a key upon seeing a blue screen. The time to press the key (in seconds) is measured and the same person is then asked to press a key upon seeing a red screen, again with the time to react measured. The results for six study participants are shown. Does the evidence suggest that the median reaction time to the blue stimulus is different from the median reaction time to the red stimulus? Use the $\alpha=0.05$ level of significance. $$ \begin{array}{ccc} \text { Participant } & \text { Reaction Time Blue } & \text { Reaction Time Red } \\ \hline 1 & 0.582 & 0.408 \\ \hline 2 & 0.481 & 0.407 \\ \hline 3 & 0.841 & 0.542 \\ \hline 4 & 0.267 & 0.402 \\ \hline 5 & 0.685 & 0.456 \\ \hline 6 & 0.450 & 0.533 \\ \hline \end{array} $$

A nerve conduction velocity test (NCV) is an electrical test that is used to evaluate the function of nerves. A NCV on a patient's sciatic nerve (length of 0.80 m) reveals a conduction velocity of 50 m/s. how long did it take the impulse to travel along the nerve? please explain how 0.016 s 40 s 0.80 s 63 s
