The amount of warpage in a type of wafer used in the manufacture of integrated circuits
Chapter 4, Problem 6(choose chapter or problem)
The amount of warpage in a type of wafer used in the manufacture of integrated circuits has mean \(1.3 \mathrm{~mm}\) and standard deviation \(0.1 \mathrm{~mm}\). A random sample of 200 wafers is drawn.
a. What is the probability that the sample mean warpage exceeds \(1.305 \mathrm{~mm}\)?
b. Find the 25th percentile of the sample mean.
c. How many wafers must be sampled so that the probability is 0.05 that the sample mean
exceeds 1.305?
