Two different computer processors are compared by measuring the processing speed for different operations performed by computers using the two processors. If 12 measurements with the first processor had a standard deviation of $0.1 \mathrm{GHz}$ and 16 measurements with the second processor had a standard deviation of $0.15 \mathrm{GHz}$, can it be concluded that the processing speed of the second processor is less uniform? Use a 0.05 level of significance. What assumptions must be made as to how the two samples are obtained?
