If the t ratio for the slope of a simple linear regression equation is equal to 1.614 and the critical values of the t distribution at the 1 percent and 5 percent levels of significance, respectively, are 3.499 and 2.365, then the slope is
A) not significantly different from zero.
B) significantly different from zero at both the 1 percent and the 5 percent levels.
C) significantly different from zero at the 1 percent level but not at the 5 percent level.
D) significantly different from zero at the 5 percent level but not at the 1 percent level.
