Examine the possibility that the mercury arose from the polarograph.
I had done this using MINITAB as follows-
stat - basic Statistics - 2 sample t test
Here, we have to test,
H0: mu1 -mu2=0 Vs mu1-mu2 <0It gives output as follows-
From above P-value is greater than l.o.s. Thus, reject H0. Hence there is possibility that mercury arose from polarograph.
