Answer:
To test :
H0 : Row means are all equal
vs.
H1 : Atleast one mean is different .
Test statistic :
We reject the null hypothesis or H0 if the observed
value of
,
where ,
The value of the test statistic :
Critical value :
Now ,
Hence we accept the null hypothesis or H0 .
Thus the row means are all equal . Thus the airlines doesnot have a significant effect on the on-time arrivals .
To test :
H0 : Coloumn means are all equal
vs.
H1 : Atleast one mean is different .
Test statistic :
We reject the null hypothesis or H0 if the observed
