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 X₂'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

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 1,X2�2, X10 10. Thus, the Xi◆◆'s are i.i.d. and have the same
distribution as X◆. We obtain the following values (in pounds):
