Asked by Abenaa
In planning a study of the birth weights of babies whose mothers did not see a doctor while pregnant, a researcher writes the hypotheses as H0: x̄ = 2250 grams versus H1: x̄ < 2250 grams. What is wrong with this?

Why is it only a one-tailed hypothesis? Is the researcher not interested in larger babies?
If interested:
H1: mean ≠ 2250
If interested:
H1: mean ≠ 2250
