The Scottsdale fire department aims to respond to fire calls in 5 minutes or less, on average. Response times are normally distributed with a standard deviation of 1 minute 36 seconds. Would a sample of 18 fire calls with a mean response time of 5 minutes 15 seconds provide sufficient evidence to show that the goal is not being met at a = .01? (a) Choose the appropriate hypotheses. a. He: ≤ 5 min vs H₁: > 5 min, Reject He if Zealc > 2.326 b. He: 25 min vs H₁: 2.326 O a Ob (b) Calculate the value of the test statistic.
