Consider the non-parametric methods for creating confidence
intervals for a single mean and hypothesis testing for a single
mean. Answer each of the following questions with one of the
following options: confidence interval estimation, hypothesis
testing, both, or neither.
a. (1 point) Which method involves shifting the sample data?
b. (1 point) Which method creates a distribution that is
centered at the observed sample mean?
c. (1 point) Which method involves using sample data and
sampling with replacement?
d. (1...

Confidence Intervals & Hypothesis Tests
The manager of a restaurant wants to know if there is a
correlation between the amount of a customer’s bill and the percent
that they tip. In other words, as people spend more money, do they
tend to tip at different rates? With data from a random sample of
157 receipts, he used StatKey to construct a 95% bootstrap
confidence interval for r. The results were: [0.018, 0.292].
A. If the manager wanted to conduct...

As we have seen in class, hypothesis testing and confidence
intervals are the most common inferential tools used in statistics.
Imagine that you have been tasked with designing an experiment to
determine reliably if a patient should be diagnosed with diabetes
based on their blood test results. Create a short outline of your
experiment, including all of the following:
A detailed discussion of your experimental design.
How is randomization used in your sampling or assignment
strategy?
The type of inferential...

Part 1: z-Procedures In this part, we will use z-procedures.
z-procedures are both confidence intervals and hypothesis tests
that use a Normal distribution. They are called z-procedures
because they rely on a z-test statistic and/or a z-critical value.
So far, we can use z-procedures for a population mean knowing the
population standard deviation. In Part 1, you will use the data
file TempSample00-18.
