To evaluate the effect of a treatment, a sample is obtained from a population with an estimated mean of μ = 30, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be 32.5, with a standard deviation of s =3 a. Which statistical test is appropriate for this problem: one-sample t-test, repeated measures t-test, or independent samples t-test b.
