1. A wastewater sample contains 7.4 mg P/L PO, and 4.5 mg P/L P,0*. a. Calculate the total phosphorus as mg PL b. Find the concentrations of Poland P0,* in wastewater as mg PO/L and mg P.0. L, respectively.
3. X = b(200, p), p0 = 0.6, x = 155, the significance level is α = 0.01. The null hypothesis is p = p0, the alternative hypothesis is p > p0. Should we accepts or reject the alternative hypothesis look below: I know the answers to this problem. I just need help on finding the critical value z. PLEASE EXPLAIN
2. Let T: P(R) + P(R) be such that Tp(x) = P(1)x2 +p(1)+ p0). a) Show that T is a linear operator. b) Find a basis for Ker(T) and a basis for Range(T). c) Is T invertible? Why? d) If possible find a basis for P(R) such that [T], is a diagonal matrix. e) Find the eigenvalues and eigenvectors of S=T* - 31.

Consider the following method of estimating λ for a Poisson distribution. Observe that p0 = P(X = 0) = e(-λ) Letting Y denote the number of zeros from an i.i.d. sample of size n, λ might be estimated by λ˜ = − log(Y/n) Use the method of propagation of error to obtain approximate expressions for the variance and the bias of this estimate. Compare the variance of this estimate to the variance of the mle, computing relative efficiencies for various...
