A paper manufacturer produces packs of colored paper. The machines are set to dye 20% of the paper pink. The manager suspects the machines are producing too many pink pieces of paper. He randomly samples 100 pieces of paper and finds that 25 of them are pink. Assume that all three conditions to perform a significance test for a z-statistic are met. Calculate the Z-statistic that would be used in the significance test for this situation. ○ z = 1.15 ○ z = 1.25 ○ z = -1.25 ○ z = -1.15
