Exercise 2
Step 1. Test Set-up
Tony V. owns a house painting business in Seattle. He estimates that it takes his crew three-and-a-half days to
paint the interior of a typical house. He has no estimate of the population standard deviation, a. He is testing a
new paint that is supposed to dry faster than the paint he has been using for over thirty years. He estimates
that the average time to paint a house is 3.5 days, the new paint is just as good as the old paint and costs the
same. Research Question: Does the new paint allow him to complete a house painting job faster than the
paint he has been using? He takes a random sample of 30 homes and paints them with the new paint Here
are the results:

3.33 3.33
The population mean, j, is presumed to be 35 days and the population standard deviation, a, is unknown.
Using Microsoft Excel, find the sample mean, &, and sample standard deviation, s, and complete the
appropriate significance test.
What test statistic should you use and why? (There are three basic one-sample hypothesis tests:
1) z-test for the population mean, 2) z-test for the population proportion, and 3) t-test for the
population mean.)
Based on the research question is this a left-tailed, two-tailed, or right-tailed test?
Step 2. Select the Level of Significance, a
A 5 percent significance level has been selected.
What is the Critical Value or Values of the Test Statistic?
Step 3. State the null hypothesis (H.) and alternate hypothesis (H1)
He:
Follow the examples shown in Clear-Sighted Statistics. You must use the appropriate Greek letters and
mathematical symbols.

Step 4. Compose the decision rule using critical values not p-values. Follow the examples
shown in Clear-Sighted Statistics.
