Question 4 (1 point)

If the t-statistic ratio for the slope of a simple linear regression equation is equal to 1.614, the critical values of the t distribution at the 1 percent and 5 percent levels of significance, respectively, are 3.499 and 2.365, and the p-value for the t-statistic ratio is 0.21, then the slope is

Question 4 options:

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)	not significantly different from zero.
