1) 95% confident that the population correlation is between -.03 and .23. Based on this information, what conclusion can you make? A Both retain and reject the null hypothesis. B There is not enough information to retain or reject the null hypothesis. C Reject the null hypothesis. D Retain the null hypothesis. 2)What two elements do you need to know to calculate the t-critical value? A Sample size and chosen alpha level B Degrees of freedom and the mean C Sample size and mean D Degrees of freedom and chosen alpha level 3) T-obtained is 5.01 and t-critical is 5.45. What is the correct conclusion? A P> .05; Retain the null hypothesis B P< .05; Retain the null hypothesis C P< .05; Reject the null hypothesis D P> .05; Reject the null hypothesis
