State the null and alternative hypotheses (take round 1 scores - round 4 scores). Is this a lower tail, upper tail or two-tailed test? Use Excel to carry out the test. Use a = 0.05. What is the value of the test statistic? What is the p-value? What is your conclusion using a = 0.05? State your conclusion in words a non-statistician could understand.

find a research article that uses hypotheses. Identify the hypotheses as null or alternative. Some articles will contain more than one hypothesis. Then, look at the discussion part of the article and see if the p-values were significant and discuss how the article presented the acceptance or rejection of the hypothesis. Include the pdf of the article with your first discussion posting.

For the following problem: A) State the Null and Alternative hypotheses. B) Identify the type of test (left tailed, Right Tailed, Two tailed) and state the level of significance. C) Calculate the p-value and make a decision to either reject/not reject the null hypothesis. D) Interpret your decision in the context of the problem.

Null and research hypotheses: Using the research studies described in the previous exercise, create null hypotheses and research hypotheses appropriate for the chosen statistical test: A.Taylor and Ste-Marie (2001) studied eating disorders in 41 Canadian female figure skaters. They compared the figure skaters’ data on the Eating Disorder Inventory to the means of known populations, including women with eating disorders. On average, the figure skaters were more similar to the population of women with eating disorders than to those without...
