Researchers measured the amount of plasma carotenoids (in micrograms per milliliter) of male and female zebra finches. Here are some summary statistics from the study (note: standard error=standard deviation/sqrt(n)):

Do male and female zebra finches differ in their plasma carotenoid levels? To answer this question, the researchers tested the following hypotheses:
H0: mM = mF versus Ha: mM ≠ mF
What can we conclude at significance level 5%?
Solution: at 5% los
Option d is correct.
d. Fail to reject null hypothesis.
