One advantage of a matched subjects design is: Group of answer choices A. Individuals do not have to be randomly assigned. B. Everything is automatically counterbalanced. C. That error variance is decreased. D. There are no individual differences.

c

Step-by-step explanation:

A matched subject design makes use of different sets of  experimental groups for a treatment. then, each test subject in one group is matched with another equivalent subject in another group.

the advantage of this is that it reduces the error of variance

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
