Answer:

Because the test statistic is less than the critical value, we can reject the null hypothesis  and conclude that the population correlation coefficient is less than zero.

Explanation:

Because the question is based on the hypothesis test of the significance of the correlation coefficient to decide whether the linear relationship in the sample data is strong enough to use to model the relationship in the population. If the tests concludes that the correlation coefficient is not significantly different from zero, it means that the correlation coefficient is not significant.
