a) The population is all of the flights belonging to the particular airline. It's not all flights in general because the airline does not have control over a rival company's flight schedule.
------------------
b) The sample is the 5 airlines the company selected. Ideally the sample should represent the population as much as possible. The larger the sample, the more representative the sample is.
------------------
c) No, the sample is likely <u>not</u> representative because one day of flight does not represent the entire lifetime of all flights done so far for that company. This particular day could have been a very good day with good weather, which may explain why the 5 flights were all on time.
------------------
d) It would be better for the company to select the days at random and sample all of the flights for those particular days chosen. This is a cluster sample. Each cluster is a day. Also, I think more flights should be sampled. Five flights does not seem like enough.

The 10th position is the 6 right after the dot. The numeral right after the 6 is closer to the next number. So by rounding it, it becomes 9.7 If the digit to the right is 5 or more, you go up a numeral. If it is 4 or less, you keep it at the numeral that it is. If it had been 9.64 then we would have kept it at 9.6 Hope this helps
