Need help with the question asap!!

ables (z, 1, F and Chi-Square) Standard Normal Distribution Table (z 0) Chi-Square Distribution Table F Distribution Table (a - 01) F Distribution (a = 025) F Distribution Table (a - .05) F Distribution Table (a =10) * Distribution Table (d( = 1, 2, ..., 35) t Distribution Table (of = 36, 37, , 0) Question 19 Which of the following statements is truc about linear regression analysis of quantitative variables? The purpose of simple linear regression is to investigate if there exists a linear relationship between a response variable and an independent 2 points (explanatory) variable. The correlation coefficient value (r) is always positive and must be between 0 and 1. The observed values of Y will fall on the estimated regression line, while the predicted values of Y will vary around the regression line. If the purpose of our regression model is prediction, it does not matter which variables we define as the explanatory and response variable
