States. Flights that arrive within 15 minutes of schedule are considered on time. Using sample data consistent
with Bureau of Transportation statistics, in January 2001, a sample of 924 flights showed 742 on time and in
January 2002, a sample of 841 flights showed 714 on time. Test the hypothesis at a 0.05 level of significance
to determine whether the major airlines improved on-time flight performance during the one-year period.
Compute for:
- null and alternative hypothesis in words
- level of significance and critical value/s and region (graph it please)
