To evaluate the effect of a treatment, one sample of n=8 is obtained from a population mean: u=40 and the treatment is administered to the individuals in the sample After the treatment, the sample mean is found to be M=35.

1. If the sample variance is S2=32, are the data sufficient to conclude that the treatment has a significant effect using a two tailed test with aplha .05. State both experimental and statistical Hypotheses, and state you decision regardingH0.

2 If sample variance is S2=72, are the data sufficient to conclude that the treatment has a significant effect sing a two-talied test with aplha .05?
