RESEARCH METHODOLOGY LESSON 20: PRINCIPLE OF HYPOTHESIS TESTING So far we have talked about estimating a confidence interval along with the probability (the confidence level) that the true population statistic lies within this interval under repeated sampling. We now examine the principles of statistical inference to hypotheses testing. By the end of this chapter you should be able to • Understand what is hypothesis testing • Examine issues relating to the determination of level of How is this

1. Using the information contained in the case‚ conduct a five-forces analysis of the U.S. Steel industry. What conclusion can you draw from this? Degree of Rivalry: Mini mills were being used by the foreign competition which mean they were able to produce steel at less expensive rates passing that on ot their customers. Barriers to entry: Starting in the 1970’s since there were no trade barriers companies overseas were able to manufacture and sell steel for a much lower price here in the United

Describe the operon hypothesis and how it explains the control of the messenger RNA production and the regulation of protein synthesis in bacterial cells. The operon is a group of genes coding for proteins with related functions and they are arranged in units. The operon is made up of the promoter‚ structural genes and the operator. Transcription depends on the regulator‚ it may be located anywhere on the bacterial chromosome. The regulator codes for the repressor‚ which binds to the operator

points out directly into the hypothesis. Hypothesis: A research hypothesis can stand for a test of time‚ it must be testable‚ talks about the current knowledge‚ and also realistic. "A hypothesis is a logical supposition‚ a reasonable guess‚ an educated conjecture. It provides a tentative explanation for a phenomenon under investigation." (Leedy and Ormrod‚ 2001). A hypothesis is important because it guides the research. A researcher may refer to the hypothesis to direct his or her thought
