1-Generate a hypothesis for a study that would be of your interest. Then write out the 8 famous steps that you would use to apply a statistical test to your generated hypothesis. 2- In statistics we may compute a result that is statistically significant but not meaningful- give an example of this. 3- After reviewing type I and type II errors- Why shouldn’t the researcher always set their confidence level at .0001- explain using type I and type II errors analysis. 4. Given the following information and setting the level of significance at .05 for decision making , would your decision do to reject or fail to reject the null hypothesis? Provide an explanation of your conclusions. a. The null hypothesis that there is no relationship between the type of music a person listens to and his propensity for crime (p < .05) b. The null hypothesis that there is no relationship between the amount of coffee consumption and GPA (p = .62) c. The research hypothesis that a negative relationship exists between the number of hours worked and level of job satisfaction (p = .51) 5 Whats wrong with the following statement? a.A Type I error of .05 means that 5 times out of 100 experiments, we will reject a true null hypothesis. b.It is possible to set the Type I error rate to zero c. The smaller the Type I error rate, the better the results
