Question:
Let X be the weight of a randomly chosen individual from a population of adult men. In order to estimate the mean and variance of X, we observe a random sample X1,X2,⋯ ,X10. Thus, the Xi's are i.i.d. and have the same distribution as X. We obtain the following values (in pounds):
165.5, 175.4, 144.1, 178.5, 168.0, 157.9, 170.1, 202.5, 145.5, 135.7
Find the values of the sample mean, the sample variance, and the sample standard deviation for the observed sample.

During the course of my study, I have worked as a private tutor. I have taught Maths and Physics to O'Level and A'Level students, as well as I have also taught basic engineering courses to my juniors in the university. Engineering intrigues me alot because it a world full of ideas. I have passionately taught students and this made me learn alot. Teaching algebra and basic calculus, from the very basics of it made me very patient. Therefore, I know many tricks to make your work easier for you. I believe that every student has a potential to work himself. I am just here to polish your skills. I am a bright student in my university. My juniors are always happy from me because I help in their assignments and they are never late.
