Question 4 options: A weak negative correlation exists C A regression line could be calculated and could be used to make accurate predictions since no strong correlation exists A positive correlation exists at the 5% level of significance C No significant linear correlation exists, but there might be a significant non-linear relationship between x and y No regression line could be calculated from these ordered pairs H
