Discuss the below:
To evaluate the effect of a treatment , a sample of n=9 is obtained from a population with a mean of m=40 and the treatment is administered to the individuals is found to be M-33
A: If a sample has a standard deviation of s=9, are the data sufficient to conclude that the treatment has a significant effect using a two tailed test with a level of significants of 0.5?
B: If the sample standard deviation is s=15,are the data sufficient effect to conclude that the treatment has a significant effect using a two tailed effect with a level of significants of =0.5
C: Comparing your answers for parts a and b,how does the variability of the score in the sample influence the out come of the test hypothesis
