Q. 2A large shipment of TV sets is accepted upon delivery if an inspection of ten randomly selected TV sets yields no more than one defective TV. The binomial probability distribution is often used in situations similar to this one, namely, large populations sampled without replacement. Explain why the binomial yields a good estimate.
Q. 3In all cases, the sum of the deviations of the measurements from their mean is 0.

Q. 4A large shipment of TV sets is accepted upon delivery if an inspection of ten randomly selected TV sets yields no more than one defective TV. Find the probability that this shipment is not accepted if 10 of this shipment is defective.
Q. 5When all the numbers in the data set are the same, the standard deviations must be zero.
