Prb5 z test of hypothesis for the proportiondirections arrival dela

1. Prb5Z Test of Hypothesis for the
ProportionDIRECTIONS:Arrival Delay(negatives mean it
arrived early)On time flights. A flight is on time if it arrives no
later than 15 minutes after the scheduled arrival time. Test the
claim that made by CNN that 79.5% of flights are on time. Use
a .05 significance level.-32How many flights are in this
