Century Business Products tested 180 computers with 8-bit micro-controllers and found that 13 failed to perform adequately on a compliance test. The same test was applied to a sample of 67 32-bit CPU's and 7 of those failed. Use the .05 level of significance to test if it is reasonable to conclude that the 32-bit machines are not performing as well as the 8 bit ones?
