Question:
Thermal resistance tests on 13 samples of Enterococcus hirae, present in milk, yield the following results in degrees Celsius:
Another set of seven samples of milk was tested after pasteurization to determine whether thermal resistance had been increased by pasteurization of milk, with the following results:
Use the 0.02 level of significance to test whether it is reasonable to assume that the two samples come from populations with equal variances.
