Cl for two mean independent data One of the town council members believes that the Northern fire station has a faster mean response time. Use an \( 80 \% \mathrm{Cl} \) to investigate their claim. Let the northern data be from population 1 and the southern data be from population 2 . The average time it takes the Northern Fire Station to respond (arrive at the scene from the phone call) from 40 randomly chosen calls is 7.5 minutes, with a standard deviation of 3.81 minutes. The average response time for the Southern Fire Station based on 45 randomly selected calls is 10.2 minutes, with a standard deviation of 4.22 minutes. F: Variable being looked at here: Parameter of Northern: R: What is that value for the degrees of freedom here? E: Calculate and write the \( 80 \% \mathrm{Cl} \) for two independent means: (2-points) D: \( \quad \) Conclusion based on Ci (explain in practical terms please / story context). (2-points) Additionally, Run a HT to see if Northern Fire Station respond faster. (3 pts.) Ha: p -value: Conclusion:
