Flights Refer to the flight numbers listed in the first column of Data Set 15 in Appendix B. What value is obtained when those 48 numbers are added and the total is then divided by 48? (This result, called the mean, is discussed in Chapter 3.) Does the result have any meaning?

Answer :

Step 1 of 1 :

Given, 48 flight numbers

1+1+1+1+1+1+1+1+1+1+1+1+3+3+3+3+3+3+3+3+3+3+3+3+19+19+19+19+19+19+19+19+19+19+19+19+21+21+21+21+21+21+21+21+21+21+21+21

Therefore, we have to add all these 48 values and divide by 48

I.e, 528/28 = 18.857

We have only flight numbers and are not used to measure anything.

This result does not mean anything.
