68% powered. Do not use the personal pronoun Tin your report. 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: Number of Days to Paint House Assignment04.pdf Page 2 of 3 Assignment 04: Chapters 13 & 14 3.40 3.75 3.33 3.50 3.33 3.50 3.00 3.40 3.50 3.40 3.00 2.85 3.25 3.00 3.50 3.50 3.33 3.33 2.75 3.50 2.75 3.40 3.33 3.50 3.50 0.33 3.40 3.85 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. E s> < Step 4. Compose the decision rule using critical values not p-values.
