Chapter 4.5, Problem 174E

a.

To determine

Calculate the sample mean for the data.

b.

To determine

Create a new dataset in which the null hypothesis is true.

Compare the sample size and standard deviation of the original dataset to the new dataset.

c.

To determine

Generate one randomization sample with replacement for the new data values obtained in Part (b).

List the values and calculate its sample mean.

d.

To determine

Generate 10 samples for a randomization distribution.

Calculate the sample mean for each case and create a dotplot.

Locate the original sample mean on the dotplot.
