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) \(\mu _ { X } = 0.529 , \sigma X = 0.475\)
