Researchers measured the amount of plasma carotenoids (in micrograms per milliliter) of male and female zebra finches. Here are the summary statistics from the study:
$\begin{array} { | l | l | l | l | } \hline \text { Sex } & \boldsymbol { n } & \text { Mean } & \text { Standard Error } \\\hline \text { Males } & 50 & 31.77 & 1.85 \\\hline \text { Females } & 52 & 29.74 & 2.02 \\\hline\end{array}$ Do male and female zebra finches differ in their plasma carotenoid levels? To answer this question, the researchers tested the following hypotheses:
?
H₀: ?_M=?_F versus ?_M??_F
What is the numerical value of the two-sample t statistic?
