Question 20 5 Points A magazine tested paints. The table below shows the overall quality score and cost in dollars per gallon. Use the rank correlation coefficient to test for a correlation between the two variables. Use a significance level of alpha = 0.05. Based on these results, do you get better quality paint by paying more? Quality | 67 | 76 | 68 | 63 | 65 | 61 | 79 | 76 | 62 | 60 | 56 Cost | 27 | 28 | 30 | 24 | 22 | 18 | 27 | 24 | 20 | 18 | 22 A. Reject the null hypothesis that there is no correlation between quality and cost. It appears that you can expect to get higher quality by purchasing more expensive paint. B. Fail to reject the null hypothesis that there is no correlation between quality and cost. It appears that you can expect to get higher quality by purchasing more expensive paint. C. Reject the null hypothesis that there is no correlation between quality and cost. It appears that you cannot expect to get higher quality by purchasing more expensive paint. D. Fail to reject the null hypothesis that there is no correlation between quality and cost. It appears that you cannot expect to get higher quality by purchasing more expensive paint.

Consider a transmission electron microscope with the following parameters: Accelerating voltage: 100 kV Beam current: 20 nA Brightness (β): $10^{12}$ A/(m²·sr) Angular spread (α): 10 mrad Energy spread (ΔE): 5 eV Spherical aberration coefficient ($C_s$): 10 mm Chromatic aberration coefficient ($C_c$): 10 mm Calculate: (a) Radius due to spherical aberration: $r_{sph} = C_s \alpha^3$ (6%) (b) Radius due to chromatic aberration: $r_{chr} = C_c \frac{\Delta E}{E} \alpha$, where E = 100 keV (6%) (c) Diffraction-limited radius : $r_{th} = 1.22\lambda/\alpha$ (6%) (d) Total practical resolution ($r_{tot}$) resulting from contributions of items (a) to (c) (6%)

17. An EMS helicopter has been called to transport a critically ill neonate to a neonatal specialty hospital. Family Members are unable to fly with the baby Because of sheer lack of cabin room. How should the flight crew relate this information to the family? A.Spend Extra time explaining the transfer process to make sure the family understands how to get to the hospital and to let them know what to expect when they arrive. B. Prepare the patient for transfer as they normally would and let the family know the weight situation as they are departing Toward the EMS helicopter. C. Ask the Hospital staff to handle the familys question and prepare to depart as soon as the patient is secured to the stretcher and ready for transport. D. Have a Crew member stay behind at the sending hospital and allow family member to fly with the patient to the receiving hospital.
