Historically, the average arrival rate at an airport is 195 flights per hour. The population standard deviation is known and is equal to 13. Airport management would like to increase arrivals so they implemented a new traffic control procedure. After implementing the new procedure, a sample of arrivals during 30 days was collected and showed a mean arrival rate of 200 flights per hour. Using a = 0.1, does the sample show that the new procedure is effective? (a) State the null and alternative hypotheses a. Ho: ≥195 Η: μ < 195 b. Ho: ≥ 200 H₁: <200 c. Ho: HS 195 H₁: > 195 d. Ho: μ= 195 e. H₁:195 Ho: ≤200 H₁: >200 (b) Calculate the test statistic of a. -2.11 b. 197.26 c. 2.11 d. 117.84
