True or false 1) Chi-square test statistic is always positive. 2) When doing linear regression, the sign of the slope is always same as the sign of the correlation coefficient. 3) A slope that is not statistically significantly different than zero indicates no linear relation between two variables, X and Y. 4) Confidence interval of the estimated slope is always wider than prediction interval.
