Will your flight get you to your destination on​ time? To the right are a histogram and summary statistics for the percentage of delayed arrivals each month from 2001 thru 2006. Consider these data to be a representative sample of all months. There is no evidence of a time trend.​ (The correlation of Flights Delayed​ % with time is requals 0.004​.) Complete parts a through c below.

Check the assumptions and conditions for inference about the mean. Select all that apply.

Find a​ 99% confidence interval for the true percentage of flights that arrive late.

​c) Interpret this interval for a traveler planning to fly. Choose the correct answer below.

Create a two column frequency HISTOGRAM for the time (in seconds). Pets/No Pets. You can decide the class boundaries. 0 – 49 seconds, 50-99 seconds, etc. Whatever seems appropriate.Two bars in each time interval. Make them different colors, side by side.   Draw one box & whisker plot for the aggregate (all) “eccstatistics” results, adding both pets/no pets responders together as one group. We are measuring time by seconds.Include a 5-number summary. I have no clue what I am doing. Player...
