The mean arrival rate of flights at O'Hare Airport in marginal weather is 195 flights per hour with a historical standard deviation of 13 flights. To increase arrivals, a new air traffic control procedure is implemented. For the next 30 days of marginal weather, the number of flights is recorded in the table below: 210 215 200 189 179 196 193 209 215 192 202 195 199 188 174 176 197 199 200 213 202 181 196 210 225 195...

The mean arrival rate of flights at O’Hare Airport in marginal weather is 195 flights per hour. To increase arrivals, a new air traffic control procedure is implemented. a) State the Hypothesis to show there has been a significant increase in the mean number of arrivals per hour. b) To test the hypothesis, O’Hare Airport takes data on the next 30 days with marginal weather. The data appear in the Airport worksheet of the Hypothesis Tests HW data workbook on...
7. The average number of planes that arrive at O'Hare Airport (Chicago) per hour was 195 with a historical (known) standard deviation of 13. To increase arrivals, a new air traffic control procedure was implemented. The number of planes that arrived per hour was collected for each of the 30 hours immediately following implementation. Those data are below. 210 193 199 215 200 209215 188 174 1 89 192 176 200 213 179196 2 02 195 202 225 195 181...
1. The mean arrival rate of flights at O’Hara International Airport in marginal weather is 195 flights per hour with a population standard deviation of 13 flights per hour. To increase arrivals, a new air traffic control procedure is implemented. In the next 30 days of marginal weather, the mean number of arrivals increased to 200. Given this information, please answer the following questions: A. Compute the standard error of the sampling distribution of mean arrival rates? B. What assumption...
