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

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

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...

Describe type I and type II errors for a hypothesis test of the
indicated claim. A shoe store claims that at least 80% of its new
customers will return to buy their next pair of shoes.
Describe the type I error. Choose the correct answer below:
a) A type I error will occur when the actual proportion of new
customers who return to buy their next pair of shoes is no more
than 0.80 but you reject H0: p≤0.80.
