A study was conducted comparing two dependent samples with the statistical hypotheses $H_0: \mu_d = 0$ and $H_1: \mu_d < 0$. The following data was collected: | Sampling Unit | Before | After | |---|---|---| | 1 | 67.9 | 68.4 | | 2 | 72.6 | 81.3 | | 3 | 45.1 | 46.7 | | 4 | 47.8 | 45.2 | | 5 | 53.4 | 64.2 | | 6 | 77.3 | 90.4 | | 7 | 42.8 | 39.6 | | 8 | 52.1 | 57.4 | | 9 | 39.2 | 38.5 | | 10 | 63.6 | 74.5 | Against a significance level of $\alpha = 0.05$, calculate a confidence interval which would support the result of the hypothesis test. [-19.372, 10.492] [-8.798, -0.082] $(-\infty, 7.885)$ $(-\infty, -0.909]$

2. Will the actual experimentally-determined dilution solution concentration be higher, lower, or the same as the theoretical concentration for the following scenarios? Briefly explain your reasoning. a. The student measures the mass of salt needed to make a 0.0750 M solution into a tared, 100 mL beaker and then records the mass onto their Data Sheet. After removing the beaker, the student notices that some of the salt landed directly on the balance pan instead of in the beaker. The student cleans off the pan and uses the measurement they originally recorded.
When two electrical resistors with resistance \( R_{1}>0 \) and \( R_{2}>0 \) are wired in parallel in a circuit, as shown in the figure to the right, the combined resistance \( R \), measured in ohms ( \( \Omega \) ), is given by \( \frac{1}{R}=\frac{1}{R_{1}}+\frac{1}{R_{2}} \). Complete parts (a) through (d) below. a. Estimate the change in \( R \) if \( R_{1} \) increases from 3 ohms to 3.02 ohms and \( R_{2} \) decreases from 4 ohms to 3.98 ohms. First determine the equation for dR. Choose the correct answer below. A. \( \Delta R \approx d R=\frac{1}{R_{1}} d R_{1}+\frac{1}{R_{2}} d R_{2} \) B. \( \Delta R \approx d R=-\frac{1}{R_{1}^{2}} d R_{1}-\frac{1}{R_{2}^{2}} d R_{2} \) c. \( \Delta R \approx d R=\frac{1}{R_{1}^{2}} d R_{1}+\frac{1}{R_{2}^{2}} d R_{2} \) D. \( \Delta R \approx d R=\frac{R_{2} d R_{1}+R_{1} d R_{2}}{\left(R_{1}+R_{2}\right)^{2}} \) E. \( \Delta R \approx d R=\frac{R_{2}^{2} d R_{1}+R_{1}^{2} d R_{2}}{\left(R_{1}+R_{2}\right)^{2}} \) F. \( \Delta R \approx d R=\frac{R_{2} d R_{1}+R_{1} d R_{2}}{R_{1}+R_{2}} \) G. \( \Delta R \approx d R=\frac{R_{2}^{2} d R_{1}+R_{1}^{2} d R_{2}}{R_{1}+R_{2}} \) H. \( \Delta R \approx d R=-\frac{1}{R_{1}} d R_{1}-\frac{1}{R_{2}} d R_{2} \)
7. Merle works on a cement crew. Merle makes $20 per hour regularly. On Friday, Merle spent 4 hours working at the Whitley house. One of these hours was spend just sitting around (idle time) waiting for the cement truck to be repaired - but Merle still got paid for that hour. Thus, Merle got paid $80 for the day. How much of his time will be considered direct labor and be directly allocated to the Whitley job? a. $0 b. $20 c. $60 d. $80
Problem 12. Evaluate the following double integral $\iint_D f(x, y)dA$ (a) $f(x,y) = 2x + 3y$, $D = \{0 \le x \le 1, 0 \le y \le 2\}$ (b) $f(x,y) = 4x$, D is bounded by the curves $y = 4 - x^2$, $y = 3x$, $x = 0$
