To evaluate the effect of a treatment, a sample of n=6 is obtained from a population with a mean of µ=80, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M=72. a. If the sample variance is s²=54, are the data sufficient to conclude that the treatment has a significant effect using a two-tailed test with α=.05? b. If the sample variance is s²=150, are the data sufficient to conclude that the treatment has a significant effect using a two-tailed test with α=.05? c. Comparing your answers for parts a and b, how does the variability of the scores in the sample influence the outcome of the hypothesis test?

According to the Official Stage Magician Handbook, magic rabbit weight (Ibs.) is normally distributed with u = 6.2 and o = 1.5. %3D Consider obtaining a random sample of 3 magic rabbits. Would it be unusual for the sample mean to be at least 6.5? Why or why not? Yes because the z-score corresponding to a sample mean of 6.5 would be z = 0.34. No because the z-score corresponding to a sample mean of 6.5 would be z = 0.34. O Yes because the z-score corresponding to a sample mean of 6.5 would be z = 0.20. O No because the z-score corresponding to a sample mean of 6.5 would be z = 0.20.
