STATCRUNCH STEPS FOR CONFIDENCE INTERVAL AND HYPOTHESIS TESTING CALCULATIONS (WEEKS 4 AND 5)
Several years ago, a government agency reported the default rate (the proportion of borrowers who default on their loans) on a certain type of loan at
0.045 Set up the null and alternative hypotheses to determine if the default rate this year is greater than 0.045.

The following are a few problems on hypothesis testing. The
corresponding confidence interval
(CI) question is also asked. This is a good practice for students
to see how hypothesis testing
results reflect in the confidence interval estimates. In the first
problem, the steps are given to get
the hypothesis testing results and the CI estimates. It is a good
practice to follow the steps. Try to
use the same steps in the subsequent problems.

In each problem show all steps of the hypothesis test or
confidence interval. If some of the assumptions are not met, note
that the results of the test or interval may not be correct and
then continue the process of the hypothesis test or confidence
interaval.

Confidence Interval & Hypothesis Testing for a
Single Population
Dominick Aldo owns and operates Carolina’s which is an Italian
restaurant in New York. The file Single
Population.xlsx is shown below and contains the amount of
time that 90 tables were seated.
Develop a 90% confidence interval for this random sample and
interpret the results.
Test the hypothesis that the average table time exceeds 98
minutes using α=.05.
What is the p-value? Interpret the results....

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...

Using either hypothesis testing or confidence interval method
solve: The average size of a farm green county is 199 acres, and
the average size of a farm in yellow county is 191. Assume the data
were obtained from two samples with standard deviations of 12 acres
and 38, respectively, and the sample sizes are 10 farms from Green
county and 8 farms from in Yellow County. Can it be concluded at
alpha= 0.05 that the average size of the farms...
