Which of the following statements is true?

• A)If the confidence interval estimate for the regression slope coefficient crosses over zero,the average change in y for a one-unit change in x may be zero.
• B)If the regression slope coefficient is very close to zero,this means that the relationship between the x ands y variable is statistically insignificant.
• C)A statistically significant regression slope coefficient indicates that for a one-unit change in y there will be a positive change in x by an amount equal to the regression slope coefficient.
• D)It is acceptable to make predictions for y using x values that are outside the range of the data that was used the in the regression.
