Aresearcher selects a sample from a population with μ = 30 and uses the sample to evaluate the effect of a treatment. after treatment, the sample has a mean of m = 32 and a variance of s2 = 6. if cohen’s d is used to measure the size of the treatment effect, which of the following would have no effect on the value of cohen’s d?

366

step-by-step explanation:

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
