Researchers Examined the Bill Color (In Hue Degree) of Male

Researchers examined the bill color (in hue degree) of male and female zebra finches. Here are the summary statistics from the study:
$$\begin{array} { | l | l | l | l | } \hline \text { Sex } & \boldsymbol { n } & \text { Mean } & \text { Standard Error } \\\hline \text { Males } & 59 & 2.91 & 0.19 \\\hline \text { Females } & 60 & 7.42 & 0.32 \\\hline\end{array}$$ We are interested in testing the following hypotheses:
H₀: ?_M=?_F versus ?_M??_F
What can we conclude from the 95% confidence interval for the difference in mean bill color ?_F-?_M (in hue degree) ?

A) Reject the null hypothesis at significance level alpha 5%
B) Fail to reject the null hypothesis at significance level alpha 5%
C) Reject the alternative hypothesis at significance level alpha 5%
D) Fail to reject the alternative hypothesis at significance level alpha 5%
