question 2

Essay

The size of an infant's thyroid can predict the health of that infant. A journal article has been submitted describing a study where the researchers wanted to see if there were differences in thyroid volume size between infants born prematurely and those born full term. You have been asked to review the journal article and find the statement, "Thyroid volume was found to be skewed, so we employed a nonparametric test to investigate the following hypothesis: H₀: µ₁ - µ₂ = 0 vs. H₁: µ₁ - µ₂ 0; the mean differences between the two groups are not different versus they are different." Critique the statement.
