Consider Target's profitability (earning power) situation and select the statement that most closely applies to the change in its position from 2022 to 2023. 1) Target's profitability ratios show a mixed conclusion, with some ratios showing an improvement and some ratios showing a deterioration from 2022 to 2023. 2) Target's profitability increased compared to the prior year because of a better return on assets, gross margin, and profit margin. 3) Target's profitability declined in the current year (2023) as compared to the prior year (2022) due to the lower debt to assets ratio. 4) Target's sales declined substantially compared to the prior year, indicating a significant decline in profitability.

3. (25 points) A shifted-version of the Cauchy distribution has the PDF $f(x, z) = \frac{1}{\pi(1 + (x - z)^2)}$ (1) where the central value is $z$, which is presumed to be unknown, and it is to be estimated. An illustration of the case when $z = 1$ is shown in figure 1.

2. (i) The atomic numbers of Fluorine (F), Neon (Ne) and Sodium (Na) are 9, 10 and 11 respectively. Write down the electron configurations for the ground state of each of these elements. (ii) The elements in (i) exhibit LS-coupling. Write down all possible spectroscopic terms for these three elements. Identify the ground state term in each case. (iii) Suppose that a uniform magnetic field, B, is turned on in the z-direction. Find expressions for how the ground state terms in (ii) are split for each of the three elements when the magnetic field is in the (a) Zeeman and (b) Paschen-Back regimes. The Landé g-factor is given by: $g_j = 1 + \frac{j(j+1) + s(s+1) - l(l+1)}{2j(j+1)}$ (iv) In Hydrogen, states of a given principal quantum number $n$ have very nearly the same energy, regardless of their orbital angular momentum. Explain why this is not the case in Sodium.

Consider the case where Y is an n × 2 data matrix, containing the values of two variables and n is the number of observations. Both variables have mean of zero and variance of one. Let S be the variance covariance matrix and w be the eigenvector of S corresponding to the largest eigenvalue. In addition, let u be any arbitrary 2 × 1 vector of length 1. 1. Discuss whether the following matrix products are conformable (5 marks). • Yw • Yw' • uu' • u'u • Y'S
