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
