15 In testing the hypotheses: H0 β1 ’ 0: vs. H1: β 1 ≠ 0 , the following statistics are available: n = 10, b0 = 1.8, b1 = 2.45, and Sb1= 1.20. The value of the test statistic is:

The Null Hypothesis for this test was Ho: u1- u2 = 0. Dr. Williams Found that the t-value = 0.98603, the p-value = 0.328213, and that p < 0.05. This means his results were not significant at a 0.05 level. Therefore, we fail to reject the null. Dr. Williams can conclude there is no difference between the scores of his two Intro Psych. classes.

9. Suppose that you were asked to test H0: μ = 10 versus Ha: μ > 10 at the [pic] = 0.05 significance level and with a sample of size n = 10. Furthermore, suppose that you observed values of the sample mean and sample standard deviation and concluded that H0 be rejected. Is it true that you might fail to reject H0 if you were to observe the same values of the sample mean and standard deviation from a sample with n > 10? Why

This assignment is intended to ensure you understand some of the basic terms used in this course.

Step 1: During this step of hypothesis testing, the query is stated again as a research theory and a null theory regarding the populations. The null and research hypothesizes are the opposites of each other. This step is necessary because it explains the theory and recognizes the populations, which will be worked throughout the study.

Customers make demands on the market by routinely expressing their desire for “more”. This has been called “seeking a bigger and better deal”. The demand is for more value, and more options. As they search the marketplace for its offerings, customers are often pleased to see new suppliers. They consider the new offerings, and make decisions about changing their purchasing habits.

So the p-value for this test is 0.006. Which is smaller than the significance level 0.05, as a result I am rejecting the null hypothesis based on the p-value approach as well.

In this case, the null hypothesis has been proven and accepted. Keep in mind that the null hypothesis “predicts that the

Dynamic Aircraft has a company policy that states it must have at least two qualified suppliers for their critical materials.

Conclusion : Reject the null hypothesis. The sample provide enough evidence to support the claim that mean is significantly different from 12 .

Initially, customer X was ordering a specific type of Torsion Rod (8mm) produced by high grade Aluminum wire. Customer Y has been purchasing Steel wire Torsion rod (8mm). Wire length is 1inch. The Production team was able to meet the demands by running these separate orders in a single machine with wire straightening and cutting operation. The chamfering operation is done in separate machine. In recent past, customer X had ordered for Steel torsion rods too. The order quantity is large which requires Peterson Spring to purchase new wire straightening and cutting operation machine as well as Chamfer Operation. On the other hand, customer Y has given a new order. There is an existing order with chamfering operation and the new order with just cutting operation. The Production team found it difficult meeting the work order with current resources. The Production Team raised this issue to senior management which might create a bad reputation if failing to meet the demands of customer and delivering order on specified date. The Production Team met with Senior Management and funds were sanctioned to purchase a chamfering machine to support existing production of SUSPA Torsion rods. It is expected that Peterson Spring will be attracting new customers and few more orders of higher quantity from existing customers in next few months to come. There has never been any quality issue or reject from

importer and exporter of raw materials and per assembled parts from their vast group of certified
