discuss the four potential outcomes of hypothesis testing and
describe what is meant by type 1 and type 2 errors. provide an
example when these errors might occur

Describe each of the errors in hypothesis testing below:
(a) under what circumstances does a Type I error occur?
(b) under what circumstances does a Type II error occur?

What are the steps in hypothesis testing?
What is the goal of hypothesis testing?
What are null and alternative hypotheses?
In §9.2 the concepts of Type I and Type II errors are
introduced.Consider the situation where a husband and wife go to
the doctor’s office to each get some tests run and the doctor
accidentally mixes up their charts. The doctor comes into the
exam room with the results of the tests and declares that the wife
is NOT pregnant but...

Particle in a finite Well
Potential Barrier (Particle tunneling through potential
barrier)
Give a physical example of each case. Also describe their energy
levels.

1. In hypothesis testing, the only two legitimate outcomes are
either to not reject the null hypothesis or to reject the null
hypothesis and accept the alternate hypothesis. Notice that the
first conclusion specifically does not say to accept the null
hypothesis. Why not?
2. In all of the cases we discussed the hypothesized difference
in the mean was zero. Would it be possible to have a hypothesized
difference of something other than zero? If so can you think of...

In hypothesis testing, a Type 1 error occurs when
the null hypothesis is not rejected when the null hypothesis is
true.
the null hypothesis is rejected when the null hypothesis is
true.
the null hypothesis is not rejected when the alternative
hypothesis is true

What would be a Type I error when doing hypothesis testing?
