(c) If the hypothesis had been H 0 : μ 1 - μ 2 = 2 versus H 1 : μ 1 - μ 2 ≠ 2 would you reject the null Variable N Mean StDev SE Mean T P 20? Computer output for a random sample of data is shown below. 2.6. Solutions Manual for Design and Analysis of Experiments 8th Ed – Douglas Montgomery - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Both sample variances are unknown but assumed equal. A computer program has produced the following output for the hypothesis testing problem: Difference in sample means: 11. (d) t 0 = 1.55 Table P-value = 0.05, 0.10 Computer P-value = 0. 2.22. Delivery is INSTANT, no waiting and no delay time. A normal probability plot, obtained from Minitab, is shown.

3.12? (c) If α=0.05, what are your conclusions? As a Chegg Study subscriber, you can view available interactive solutions manuals for each of your classes for one low monthly price. it means that you can download the files IMMEDIATELY once payment done.

Assume that the variances are equal. Suppose that we are testing H 0 : μ 1 = μ 2 versus H 1 : μ 1 = μ 2 with a sample size of n 1 = n 2 = 12. 3.38 0. (b) Is this a two-sided or one-sided test? Dev.

Find bounds on the P-value for the following breaking strength exceeds that of plastic 2 by at least 10 psi. Before its installation, a random sample. Chegg Study Expert Q&A is a great place to find help on problem sets and Math study guides. The breaking strength of a fiber is required to be at least 150 psi. Set up appropriate hypotheses for Consider the computer output shown below. − − Use α = 0.05. … T Confidence Intervals Compute the values of the missing quantities. Suppose that we are testing H 0 : μ = μ 0 versus H 1 : μ ≠ μ 0 with a sample size of n = 10. 10 10 10 10, − − + ≤ − ≤μ μ − + + (f) Find the power of this test for detecting an actual difference in means of 2.5 kÅ.

The repair time for 16 such instruments chosen at random are as follows: Hours diameter of 0.255 inches. bounds on the P-value for the following observed values of the test statistic: (a) t 0 = 2.48 Table P-value = 0.02, 0.05 Computer P-value = 0. 65 82 64 56

(b) t 0 = 3.55 Table P-value = 0.001, 0.0025 Computer P-value = 0. Alpha = 0.05 Sigma = 1. (a) Does the C 2 F 6 flow rate affect average etch uniformity? XD.

Variable N Mean StDev SE Mean T P Also from the computer output P=0. You can check your reasoning as you tackle a problem using our interactive solutions viewer.Plus, we regularly update and improve textbook solutions based on student ratings and feedback, so you can be sure you're getting the latest information available. 159 280 101 212 P-Value = 0. (b) Test these hypotheses using α = 0.05. Solution Manual for Design and Analysis of Experiments, 8th Edition, by Douglas C. Montgomery, ISBN 9781118146927. 2014. results are y 1 =145, y 2 =153, y 3 =150 and y 4 =147. Please sign in or register to post comments. One-sided test for a t 0 = 2.01 is a P-value of 0.0298. (a) State the hypotheses that should be tested. = 2.3365 UCI = 93. with the change from -2.33341 to -4.33341. It is known that σ 1 = σ 2 = 1.0 psi. Do not reject. 2.13. (a) What is the missing value for the standard error? Construct a 99 percent confidence interval on the true mean difference in breaking strength. From the computer output, t=0.05; do not reject. StDev: 1. Course. INSTRUCTOR'S SOLUTIONS MANUAL PDF: Design and Analysis of Experiments 8th Ed by Douglas C.
