In general, if the variance of the difference scores increases, then the value of the t statistic will .
a. increase (move farther toward the tail of the distribution).
b. decrease (move toward 0 at the center of the distribution).
c. stay the same - the t statistic is not affected by the variance of the difference scores.
d. may increase or may decrease. There is no consistent relationship between variance and the size of the t statistic.

Abc will undergo two transformations to give aa'b'c' which pair of transformations will give a different image of aabc if the order of the transformations is reversed? a. a rotation 90' counterclockwise about the origin followed by a reflection across the y-axis b a translation 5 units down followed by a translation 4 units to the right c. a reflection across the x-axis followed by a reflection across the y-axis a rotation 180'clockwise about the ongin followed by a reflection across the y-axis reset next 2 omentum all rights reserved o atk me anything o o e

Which part of a 2-column proof is the hypothesis of the conjecture? a) given b) reasons c) prove d) statements ! i think it's b but i'm not quite

Ade and abc are similar. which best explains why the slope of the line between points a and d is the same as the slope between points a and b?
