Pumpkin patch: Suppose we plant pumpkins in a garden
where half of the plants are shaded. Then, to test a new
fertilizer, we fertilize the plants in full sun and do not
fertilize the plants in the shade. In the fall the fertilized
plants yield more, bigger, and prettier pumpkins.
Which of the following did we fail to include in the
experimental design?
1.Establish a control group
2. Direct control of confounding variables
3.Compare groups of the explanatory variable
4.Establish...

Find the temperature distribution T(r,θ,z) inside a cylinder of
height z= 20 and radius r= 8 , if the cylinder temperature is zero
in all surface except the bottom circular surface where it is
divided two halves , the first is held at T1= 100 c and the other
is held at T2=200 c.
please show me the solution with the details of the derivation
.
