A sample of n = 28 individuals is randomly selected from apopulation with a mean of μ = 65, and a treatment is administeredto the individuals in the sample. After treatment, the sample meanis found to be M = 61. If the sample standard deviation is s = 20,are the data sufficient to conclude that the treatment has asignificant effect using a two-tailed test with alpha = 0.01?
Accept the null hypothesis, there is not a significant treatmenteffect.

Reject the null hypothesis, there is not a significant treatmenteffect.
