  Indicate whether the statement is true or false

Question 2

Two variables have a correlation coefficient equal to -0.65 from a sample size of 10. Which one of the following statements describes the results of the hypothesis test that the population correlation coefficient is less than zero using  = 0.05?
 
  A) 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.
  B) Because the test statistic is less than the critical value, we can reject the null hypothesis and conclude that the population correlation coefficient is not less than zero.
  C) Because the test statistic is greater than the critical value, we can reject the null hypothesis and conclude that the population correlation coefficient is less than zero.
  D) Because the test statistic is greater than the critical value, we fail to reject the null hypothesis and conclude that the population correlation coefficient is not less than zero.
