State whether the following statements are true or false and give a brief explanation. (Note that no marks will be given without explanation.) a) A research is conducted to study the relationship between two variables. The two variables are: (i) the occupations of employees, and (ii) the happiness scores of employees. It is noted that the occupation is at nominal level and the happiness score is at interval level. To perform the analysis, the chi-square test should be used. b) You are given that the coefficient of determination of two variables is 35%. So, it can be concluded that the slope of the regression line for the two variables is positive.
