Suggest ways to investigate the significant effects and association in small samples. b. Find the odds ratio. Compute the probabilities for tables where [pic] is less than the odds ratio from the observed table as assumed under the alternative hypothesis‚ Ha. At what probability value do you find the claim to be reasonable?

Provide a rationale for your answer. In this study‚ t= -3.15 describes the mental health variable. It is significant because they are the variables being tested since the p value is 0.002 and the alpha is 0.05‚ the difference can cause the null hypothesis to be rejected. 3. Is t = −1.99 significant? Provide a rationale for your answer. Discuss the meaning of this result in this study. It is significant because the p= 0.049 value is smaller than the alpha that was set for this study (0.05). This

The word ‘Hypothesis is derived from a Greek word‚ which means ‘to suppose’. It is usually considered as the principal instrument in research. For a researcher it is a formal question that he or she intends to resolve. In this way a hypothesis may be defined as a proposition or a supposition. The main function of hypothesis is to guide the collection and processing of materials and direct the research. Hypothesis is a tentative conclusion. It is facts based theory. A research scholar will analyze

making (CTU‚ 2012). Hypothesis testing and multivariate statistics are just two examples of the statistical methods that can be used. My goal today is to present information in such a way as to assist my senior manager in better understanding hypothesis testing‚ along with the ideas of null and alternative hypotheses. The formal method used by researchers to accept or reject a statistical hypothesis is known as hypothesis testing (Easton & McColl‚ n.d.). Hypothesis testing is one of the most

differences between the t-test and z-test. Additional topics in the discussions were how hypothesis testing is crucial to determining if the hypothesis is valid or false. One way to know if the hypothesis is valid is to determine the null hypothesis‚ which the opposite of the original theory‚ and tests against the alternative hypothesis‚ which correlates with the original hypothesis. To establish if the null hypothesis is valid statistical tests can help compare the means from two groups‚ and the results
