Ten pairs of points yielded a correlation coefficient y of 0.79. If a=0.05, which of the following statements is correct if H 0:P=0? (Do not calculate a t-value.)

Because 0.79 is greater than 0.632, the null hypothesis is rejected.
Because 0.79 is greater than 0.602, the null hypothesis is not rejected.
There is no correlation between the variables.
Because 0.79 is greater than 0.632, the null hypothesis is not rejected.
