Refer to Exercise 13. a. Compute the quantity s =MSE, the estimate of the error standard deviation
Question:
a. Compute the quantity s =√MSE, the estimate of the error standard deviation σ.
b. Assuming s to be the error standard deviation, find the sample size necessary in each treatment to provide a power of 0.90 to detect a maximum difference of 2 in the treatment means at the 5% level.
c. Using a more conservative estimate of 1.5s as the error standard deviation, find the sample size necessary in each treatment to provide a power of 0.90 to detect a maximum difference of 2 in the treatment means at the 5% level?

What I have learnt in my 8 years experience of tutoring is that you really need to have a friendly relationship with your students so they can come to you with their queries without any hesitation. I am quite hardworking and I have strong work ethics. Since I had never been one of those who always top in the class and always get A* no matter what, I can understand the fear of failure and can relate with my students at so many levels. I had always been one of those who had to work really hard to get decent grades. I am forever grateful to some of the amazing teachers that I have had who made learning one, and owing to whom I was able to get some extraordinary grades and get into one of the most prestigious universities of the country. Inspired by those same teachers, I am to be like one of them - who never gives up on her students and always believe in them!
