We are planning an experiment comparing three fertilizers. We will haveExercise 7.2 six experimental units per fertilizer and wi
ll do our test at the 5% level. One of the fertilizers is the standard and the other two are new; the standard fertilizer has an average yield of 10, and we would like to be able to detect the situation when the new fertilizers have average yield 11 each. We expect the error variance to be about 4. What sample size would we need if we want power .9

Answer:
d(1) = -3 and d(2)= -28
Step-by-step explanation:
Given that the distance d, in centimeters, that a diving board bends below its resting position when you stand at its end is dependent on your distance x, in meters, from the stabilized point
For finding out the distances for x=1 and x=2
let us substitute 1 and 2 for x
d(1) = -3 and d(2)= -28
Answer:
Decreases
Step-by-step explanation:
We need to determine the integral of the DE;
We can solve this by integration by parts on the left side. We expand the fraction 1/P²:
let
Substitute u in:
Therefore the equation is:
We simplify:
As t increases to infinity P will decrease
