hw_lect3_1: I explained the intuition behind the sampling distribution. But, as I said, technically, that description is for the *empirical* sampling distribution. The sampling distribution itself is a distribution - not a histogram. For some simple problems, it is possible to analytically derive the sampling distribution itself. Let's make sure you remember how. Consider the following probability mass function: X = 1, 2, 3 p(x) = 1/2, 1/4, 1/4 Consider samples of size 2. Derive the sampling distribution of the sample mean. Follow these steps: 1) Write out all possible samples of size 2, assuming sampling with replacement. 2) Find the probability for each possibility, assuming that the two draws are independent. 3) Find the sample mean for each possibility. 4) Use the above, to find pr(sample mean =1), and pr(sample mean =1.5), ..., pr(sample mean = 3).

One hundred mL of a water sample was put into a porcelain dish that has a mass of 60.76 g. The dish + sample were dried at 105°C, and after they cooled, had a mass of 61.89 g. Two hundred fifty mL of the same water sample was filtered through a glass fiber filter. The glass fiber filter + the aluminum planchet holding the filter was previously weighed, and had a mass of 1.8644 g. After the sample was dried, the planchet, filter paper, and filtered solids were found to have a mass of 1.9117 g. The total suspended solids (mg/L) in the water sample is most nearly: Select one: A. 12 B. 190 C. 280 D. 470
