  1. The rowan (Sorbus aucuparia) is a tree that grows in a wide range of altitudes. To study how the tree adapts to its varying habitats, researchers collected twigs with attached buds from 12 trees growing at various altitudes in North Angus, Scotland. The buds were brought back to the laboratory and measurements were made of the dark respiration rate. The accompanying table shows the altitude of origin (in meters) of each batch of buds and the dark respiration rate (expressed as µl of oxygen per hour per mg dry weight of tissue).
  2. Compute the correlation coefficient
  3. calculate the least squares regression line of Y on X (y-hat= a +bx)
  4. Predict the respiration rate at an altitude of origin 720

Quinine, an alkaloid derived from a tree that grows in tropical rain forests, is used in the treatment of malaria. Like all alkaloids, quinine is a sparingly soluble weak base: 1.00 g of quinine will dissolve in 1.90 × 102 L of water. What is the pH of a saturated solution of quinine? The number of significant digits is set to 2; the tolerance is +/-4% A 27.4 mL sample of saturated quinine is titrated with 0.00843 M HCl solution....
