Question

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, ?̅ ?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
