\text { P(T<=t) two-tail } & 0.1791 & \
\text { t Critical two-tail } & 2.0860 & \
\hline
\end{array}$$ Which conclusion is correct in a two-tailed test at ? = .05?
A)There appears to be no difference in the mean occupancy rates.
B)HealthPro has a significantly higher mean occupancy rate.
C)There is a significant difference in the mean occupancy rates.

The p-value in a two-tailed test is 0.1791, which is greater than the significance level α = .05, indicating that there is not enough evidence to reject the null hypothesis. This suggests that there is no significant difference in the mean occupancy rates between MaxHealth and HealthPro.
