a) Compute the least Squares regression line for predicting auditory response time from visual response time.
b) Construct a 95% confidence interval for the slope
c) Can you conclude that visual response is useful in predicting auditory response? Use alpha=.01 in hypothesis test
d) create a labeled scatter plot of the data

Interpretation:
The scatter plot delineates the strong positive linear relationship between the quantitative variables Visual (X) and Auditory (Y). The direction of the data points is upwards. Hence, we can say that there exists a positive linear relationship between the variables.

Fast reactions: In a study of reaction times,
the time to respond to a visual stimulus x and the time to
respond to an auditory stimulus y were recorded for each
of 6subjects. Times were measured in thousandths of a second. The

A researcher hypothesizes that reaction time (RT) measured in
milliseconds in response to a startling stimulus will be lower
(faster) before people drink 5 beers than it will be afterward. A
sample of 12 patients is presented with a startling stimulus, and
their mean score is 6.08 milliseconds with an SD of 1.38. They
drink 5 beers, another startling stimulus is presented, and
participants’ mean reaction time is 14.25 milliseconds with an SD
of 3.7. The raw scores and Z-scores...

An educational psychologist is examining response times to an
on-screen stimulus. The researcher believes there might be a weak
effect from age, but expects a more pronounced effect for different
color contrasts. She decides to examine a black on white (B/W)
combination compared to 2 alternatives: red on white (R/W) and
yellow on blue (Y/B). Here is the data for response times (in
milliseconds):

Reaction time studies are studies in which participants receive
a stimulus and the amount of time it takes for them to react is
measured. In one simple type of reaction time study, each
participant holds a clicker button and stares at a screen. When the
participant sees a part of the screen light up, he or she clicks
the button as quickly as possible. The researcher then records how
much time elapsed between when the screen lit up and when...

List the pathway from stimulus to response for each of the
following.
A. Stimulus – Stubbed your toe
Response – Hop on one foot
B. Stimulus – Hit biceps tendon
Response – Elbow flexion
C. Stimulus – Smell fresh baked bread
Response : Increased thin watery saliva

"When a visual stimulus is presented to us, our visual brain
regions show two kinds of electrophysiological signals. One is fast
and comes very soon (<100 ms) after the stimulus is shown, and
can be traced to be coming from the retina through the thalamus.
The other signal is slow and comes a bit later (>300 ms) after
the stimulus, and can be traced to be coming from frontal and
parietal regions. Disrupting these later signals that come from
frontal...

The driver's reaction time in response to a particular potential
traffic hazard is the time required from the point of initial
detection of the hazard in one’s field of view to the time that
vehicle control components are actuated (such as movement of one’s
foot to the brake pedal). The following data represents the
measurements of the driver’s reaction time in seconds for the male
and female participants of the experiment:
