Please help me solve this long horrible problem. Statistics is killing me!

For the time being , the air traffic control SYSTEM in the United STATES IS run by the Federal government . SOME PEOPLE WOULD like to Change this , arguing that the air traffic control System Should be part of the private SECTOR. Among the argument= given for the privatization of air traffic control is that flight delays are much too common in the United States . A first Step in deciding if . indeed , CELEYE in the U.S. ATE TOO common" might be to Compare flight delay information from the U.S. and other nations .` SUPPOSE that You have in front of you information from Several Samples of flight: over the past Six WEEKS . Each =ample is composed of domestic flights for =\\ Certain Country . ( ONE of the Samples IS COMPOSED of flights within the U.S., One of the Sample= is Composed of flights within Canada , and So on . ! The information recordEd for Each flight is the time I 'in minutes ; that the plane WEE late to the arrival Date . "If the plane WEE Early' , then the time RECORDEd is negativE . ! EGGEd on this information , You perform & One - way , independent-Sample= ANDVA TEST Of the hypothesis that there are no differences in the mean flight delay TIME= =ITIOng the FEVEREl Countries . THE result of this ANDVA TEEt STE SUMMARIZEd in the ANDVA taGLE below .
