Apgar score is a score between 0 and 10 that gives a measure of the physical condition of a newborn infant. Researchers collected the Apgar scores of 20 pairs of identical twins. The researchers wanted to test if their results suggest a significant difference in the Apgar score between the first born twin and the second-bom twin Assume that the necessary conditions for inference were met. Which of these is the most appropriate test and alternative hypothesis?
a) Two-sample t-test with Ha: first-born second-born
b) Paired t-test with Ha: difference > 0
c) Paired t-test with Ha: difference 0
d) TWO-sample t-test with Ha:first-bom second-bom
e) TWO-sample t-test with Ha: first-born

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
