Question details
A random sample is obtained from a population with a mean of μ = 100, and a treatment is administered to the sample. After treatment, the sample mean is found to be M = 104 and the sample variance is s^{2} = 400.
(a) Assuming the sample contained n = 16 individuals, measure the size of the treatment effect by computing the estimated d and r^{2}. (Use 3 decimal places.)
d = | |
r^{2} = |
(b) Assuming the sample contained n = 25 individuals,
measure the size of the treatment effect by computing the estimated
d and r^{2}. (Use 3 decimal places.)
d = | |
r^{2} = |
