Answer:
The 95% confidence interval for the difference between the Route B and Route A commuting times is -3.771808 to 1.771808
Step-by-step explanation:
Here we have the confidence interval is given by the following equation;
= 49 Minutes
σ₁ = 2 Minutes
= 50 Minutes
σ₂ = 4 Minutes
n₁ = n₂ = 10 days
α = 0.05
At 95%, from the z score table , z =
1.959964 ≈ ± 1.96
Plugging in the values Solving we get
Δμ Min = -3.771808 and Δμ Max = 1.771808.
