    Could you please explain the step 1 and step 2 for me? I know the notes want to show the formula for E(SSTR), but I don't know what are these two steps doing. 1.2 Expectations of sums of squares Expectation of the sums of squares be derived from the following fact about sample variance. If X1, . . . , Xn are iid, with mean μ and variance σ2, then The sample variance is an unbiased estimator of the variance...

    We use the formula PV = FV (1/1+R)^N to calculate Present Value. The formula is used to figure out how much a future sum is worth today, given that there is always a discount rate. In class, we imagined a $20 million lottery win, in which the Lottery officials make the following offer: either take $1 million per year for 20 years, or accept the Present Value using a discount rate of 5%. There is a factor that is NOT...

    Please let me know if you have any questions. Thanks in advance! We want to develop a code that calculates In(1 - x) =- on the interval -1<x<1. First, understand what this notation represents. The capital sigma (2) indicates that a summation of terms is to be performed. (The term summation still applies even though all the terms are negative.) We are also given the prototype term written in terms of x and n. The notation also tells us that...

    We know copper is a transition metal that can show a +1 or +2 ionic charge. In this lab, we will use the ideas of limiting and excess reactants to determine what copper does in a really neat reaction. The reaction we will explore today is between copper and silver (I) nitrate. Since we don’t know the charge of copper, we will write two separate reactions and by doing stoichiometry calculations we should be able to determine which reaction actually...
