September 28th, 2022
If the t ratio for the slope of a simple linear regression equation is equal to 1.614 and the critical value of the t distribution at the 1% and 5% levels of significance, respectively, are 3.499 and 2.365 is the slope:
not significantly different from zero
significantly different from zero at both the 1% and 5% levels
signifcantly different fro zero at the 1% level but not at the 5% level
significantly different from zero at the 5% level but not at the 1% level.
