Babies bom seighing 2500 grams (about 5.5 pounds) or less are called low-birth-weight babies, and this condition sometimes indicates health problems for the intant. The mean birth weight for children born in a certain country is about 3449 grams (about 7.6 pounds). The mean birth weight for babies bom one month early is 2692 grams. Suppose both standard druiations are 450 grams. Also assume that the distribution of bith weights is roughly unimodal and symmetric. Complete parts a through e below. a. Find the standardined score ( z - 8 cone), relative to all biths in the country, for a baly with a bith weight of 2500 grams. Po ◻ (Phand to two thetimed photes is needed?) b. Find the standarsined score for a bith weight of 2500 grams for a child bom ore month early, using 2092 as the mean. 70 ◻ Foont to two chockul paces as reeded) 6. For which proup is a birth weight of 2500 paws more common? Explain what Tat implies. Unusual 8 -scores are far from 0. Choose the consel anvwer telow. A. A bith weight of 2500 grams is mone corrong for bables born one month early. This makes sense because babies gain weight during geotation, and babies born one month early had less tree to gain weight. B. A birh weight of 2500 graws is more common for all tirths in Phe country. This makes sense because the group of all births in the country is much larger than the group of births that are one month easty. Therefore, more babies will have low birth weights arrong al biffis in the country ◯ C. A birth weight of 2500 is equally as common to belle groups. ◻ D. It cannot be determined to which group a bith weight of 2500 grams is more common.

Problem 3 Consider the situation depicted in Figure 2: A box of mass $m = .250 kg$ slides down a frictionless rollercoaster. The total energy of the box is measured to be $E = 100 J$ as it slides down the first incline. If $v_A = 10 \frac{m}{s}$ determine a) the initial height, h, of the box. Also, determine the velocities b) $v_B$ and c) $v_C$ of the box. (Note: The initial energy of the system is taken with respect to a co-ordinate system with origin placed at ground level.) If at the end of the boxes journey it comes to a complete STOP by slamming into a spring with spring-constant $k = 100 Nm$, d) determine the amount the spring was compressed from it's equilibrium value, $\Delta x$. (Note: The height of the box when it comes to a stop against the spring is $\frac{3}{5}h$.)

4. The inverse of a matrix $A = \begin{bmatrix} a & b \\ c & d \end{bmatrix}$ is \\ $A^{-1} = \frac{1}{ad - bc} \begin{bmatrix} d & -b \\ -c & a \end{bmatrix}$, provided that $ad - bc \neq 0$ \\ If $a = 2$, $b = -3$, $c = -1$ and $d = 4$, then verify that: \\ (a) $A \cdot A^{-1} = A^{-1} \cdot A = \begin{bmatrix} 1 & 0 \\ 0 & 1 \end{bmatrix} = I_2$. \\ (b) $(A^{-1})^{-1} = A$
