In the preceding alternate example, researchers were testing a new vitamin tablet that
claims to lower a child's risk of developing attention deficit/hyperactivity disorder (ADHD).
They want to carry out a test of
H,:p=0.11
H:p<0.11
where p= the true proportion of all children like those in the study who would develop
ADHD when given the new vitamin tablet. Earlier, we mentioned that the power of the test
to detect p=0.05 using 200 subjects and a significance level of a =0.05 is 0.937.
Determine whether each of the following changes would increase or decrease the power of
the test. Explain your answers.

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
