A biologist claims that warmer temperatures affect the growth of plants. He randomly assigns 90 plants at the same stage of development to two treatment groups, 20oC or 35oC. After three months, he measures the weights of the plants and calculates the difference in mean weights of the plants for each temperature (35oC – 20oC). What is the appropriate inference procedure?

i dont know sorry

step-by-step explanation:

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
