In a chi-square test, if you are able to reject the null hypothesis at alpha = .05, you can conclude: a) there is no association between the variables b) there is some association between the variables c) there is a very weak association between the variables d) there is a very strong association between the variables The degrees of freedom for a chi-square test for a two way crosstab with four rows and three columns is: a) 9 b) 6 c) 12 d) 7 If we conducted a hypothesis test to determine if there is a linear relationship between postnatal depression scores and antenatal depression scores then which of the following would constitute a Type 2 error a) Decide that there is no relationship between the postnatal and antenatal depression scores when a significant relationship does exist. b) Decide that there is a significant relationship between the postnatal and antenatal depression scores when there is not.
