Table 6 shows the population, in thousands, of harbor seals in the Wadden Sea over the years 1997 to 2012. a. Let x represent time in years starting with x=0 for the year 1997. Let y represent the number of seals in thousands. Use logistic regression to fit a model to these data. b. Use the model to predict the seal population for the year 2020. c. To the nearest whole number, what is the limiting value of this model?

Three male patients, pink, green and blue, came into a medical clinic with symptoms of lethargy (feeling tired) and chest congestion. A blood sample was taken for each patient to measure the hematocrit levels and to determine the hemoglobin saturation curves for each patient. The results are shown below with the saturation curve on the left and the hematocrit on the right. What should the oximeter readings be for Patients Pink, Green and Blue if arterial PO₂ was 80 mm Hg [Select) ? Which patient(s) has a significant reduction in total oxygen carrying capacity [Select] #? NO, Saturation of hemoglobin 100 80 60 40 20 Pink, 40 40 PO, (mm) 30 Bue 100 Pink Green Blue
