Reference no: EM13142927

Suppose that the specifications for a certain kind of optical glass require, among other things, that the index of refraction be uniform to the extent that s must not exceed 0.0075. A random sample of 10 pieces of this glass is taken from each (large) shipment and the shipment is rejected as unsatisfactory if the sample variance is too large; specifically, if the probability of obtaining such a large value of s^2 (s(squared)), is less than or equal to 0.01 even though s = 0.0075. What is to be done with a shipment of this glass for which the sample variance of the indices of refraction equaled 0.000182?
