In a semiconductor manufacturing company, the actual size of System on a Chip (SoC) chips is normally distributed with a mean of 7 nanometers and a standard deviation of 0.7 nanometers. A random sample of 15 SoC chips is taken. i. The SoC chips with a size bigger than 7.5 nanometers are rejected. Find the percentage of chips that will be rejected. ii. If the probability of the rejected SoC chip is 1.5% of the sample. What will be the mean size of the sampling SoC chip, ?̅ ?
