The fire department of a city wants to test the null hypothesis that σ = 10 minutes for the time it takes a fire truck to reach a fire site against the alternative hypothesis σ 6= 10 minutes. What can it conclude at the 0.05 level of significance if a random sample of size n = 30 yields s = 9.5 minutes? Assume normality.
