While checking for linearity by examining the residual plot, the residuals must: A) be linearly scattered select answer below B) exhibit a linear trend C) be below the x-axis D) be independent If the correlation coefficient between the variables "age" and "price" is roughly zero, then A)"age" is not necessarily independent of "price" select answer below B) there is a linear correlation between "age" and "price" C) "age" is dependent on "price" D) "price" is independent of "age
