The first hypothesis is a claim by the researcher before conducting the study. In
statistics, this type of hypothesis is called the null hypothesis.
After the study, the null hypothesis is either accepted or rejected. The second hypothesis is dependent on the first hypothesis. It is called the alternative hypothesis. If
we reject the null hypothesis, the alternative is accepted. If we accept the null hypothesis alternative hypothesis get accepted.
In null hypothesis leading and lagging variables is used .Leading variables is baggage wait time, whereas lagging variables is Financial.
Financial results of a company would not predict baggage wait time because the direction between lag and lead are incorrectly.
Another hypothesis may be stated as ,null hypothesis is population mean time
Ho: The passenger gets their bags less than or equal to 20 min .
H1:The passenger gets their bags more than 20 min .
If this statement is true .then initial claim is false .
