Multiple Choice

Compute the Mean and Standard Deviation of a Hypergeometric Random Variable
-A manufacturer receives a shipment of 170 laptop computers of which 9 are defective. To test the shipment, the quality control engineer randomly selects 10 computers from the shipment and tests them. The random variable X represents the number of defective computers in the sample. What are the mean and standard deviation of the random variable X

A) $\mu _ { X } = 0.529 , \sigma X = 0.689$
B) $\mu _ { X } = 0.529 , \sigma _ { X } = 0.708$
C) $\mu X = 0.053 , \sigma X = 0.689$
D) $\mu _ { X } = 0.529 , \sigma X = 0.475$
