A sample of n = 25 scores is selected from a population with a mean of μ = 73 , and a treatment is administered to the sample. After treatment, the sample has M = 70 and s2 = 100. If a hypothesis test with a t statistic is used to evaluate the treatment effect, then what value will be obtained for the t statistic? t = -0.75 t = -3.00 t = -1.50 t = +1.50
