Typical machined parts require very tight tolerance in variance in order to work properly in their application. We took a sample of the length (in mm.) of 100 units from a large production run and got the following statistics: sample mean = 499.97, sample variance = 6.52 What is the 99% confidence interval estimate for the true population VARIANCE in unit length?
a. (499.30, 500.64)
b. (4.97, 8.93)
c. (4.64, 9.71)
d. (4.79, 9.32)
