b. The dependent variable is the average thickness of annual rings.
c. The independent variable is the age of the tree. d. 3.75 cm is the average thickness of rings for forest A for 40 years. e. Forest A probably had more problems such as lack of water or maybe insects than forest B. Question #3
b. The dependent variable is the days of maturity.
c. The independent variable is the amount of ethylene (mL/m^2). |
Question #2
b. The dependent variable is the number of tadpoles.
c. The independent varialbe is the pH of water. d. 6.75 is the average pH. e. 83 is the average number of tadpoles per sample. f. The optimum water pH is 6.5 pH for tadpole development. g. The greatest change of tadpoles number is 5.5 and 6.5 pH of water. h. Probably lower than 15 tadpoles would be found in a pH of 5.0. |
