Mathematical models are used as tools to describe reality. These
models are supposed to characterize the important features of the
analyzed phenomena and provide insight. The normal distribution is
an example of a random variable that is widely used by researchers
to model real data.
Researchers often model real observations using the normal
distribution, but sometimes the real distribution is a bit
different from the perfect, normal distribution. List some
reasons why researchers might make approximations like this and
describe...

Provide an example where classification would be used as the
analysis. Describe the predictor(s), the response variable, and
explain whether prediction or inference would be of primary
interest.
Provide an example of a proof by mathematical induction.
Indicate whether the proof uses weak induction or strong induction.
Clearly state the inductive hypothesis. Provide a justification at
each step of the proof and highlight which step makes use of the
inductive hypothesis.
a)
Give one example of a sentinel event that could potentially occur
in a clinical setting
b)
What type of errors/ sentinel events could potentially occur to a
patient, what interventions could you implement to prevent these
errors
" time headway" in traffic flow is the elapsed time between the
time that one car finishes passing a fixed point and the instant
that the next car begins to pass that point. Let X=the time headway
for two randomly chosen consecutive cars on a freeway during a
period of heavy flow. Suppose that in a different traffic
environment, the distribution of time headway has the form
f(x)={k/x^5, x>=2
{0, x<2.
a) Determine the value of k for which f(x)...
