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...

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.
