Answer:
this is the answer of your question
Answer:
a) H0: μEuro - μChinese = 0 vs. Ha: μEuro - μChinese > 0
b) Newborn European infants weigh more, on average, than newborn Chinese infants.
Step-by-step explanation:
<em>Null hypothesis</em> would be: infants of European descent has the same weight at birth as Chinese infants. μEuro = μChinese or μEuro - μChinese = 0
And the <em>alternative hypothesis</em> would be: infants of European descent heavier at birth than infants of Chinese descent. μEuro > μChinese or μEuro - μChinese > 0.
Because in particular infants of the European infants are considered heavier. If not, the alternative hypothesis would be μEuro ≠ μChinese
or μEuro - μChinese ≠ 0.
test a p-value of 0.001 is significant at α = .05, therefore null hypothesis is rejected in favor of alternative hypothesis Ha: μEuro - μChinese > 0, or Newborn European infants weigh more, on average, than newborn Chinese infants.
