An electronics store receives a shipment of 49 flat screen TVs of which 5 are defective. During the quality control inspection, 4 TVs are selected at random from the shipment for testing.
The random variable X represents the number of defective computers in the sample A) hypergeometric; N = 49, n = 4, k = 5, x = 0, 1, 2, 3, 4
B) hypergeometric; N = 49, n = 5, k = 4, x = 0, 1, 2, 3, 4
C) hypergeometric; N = 49, n = 4, k = 5, x = 0, 1, 2, . . . , 5
D) not hypergeometric
