Question

You find 6 statements below. Each statement is either true (T) or false (F). Write your answer in the table. A correct answer gives you 5p, an incorrect answer gives you 0p. 7. The correlation coefficient is a value between 0 and 1. 8. For the analysis of two-way tables, in a table with r rows and c columns, the number of degrees of freedom is $r \times c$. 9. In a simple linear regression model, the error term $\varepsilon$ is distributed as normal distribution with mean 0 and standard deviation 1. 10. A 99% confidence interval is wider than an 80% confidence interval. 11. When p-value is smaller than the significant level $\alpha$, we can not reject the null hypothesis. 12. The smaller the coefficient of determination $R^2$, the better the model is.
