A local veterinary clinic typically sees 15 of its horses presenting with West Nile virus Last month 100 horses were admitted and it was found that 20 of them had been infected with West Nile virus The probability of seeing 20 or more horses with West Nile virus was calculated based on a Normal distribution with 15 and standard deviation o 12 75 Which statement is TRUE O A Using the Normal approximation to the binomial distribution is justified because X 20 10 O B Using the Normal approximation to the binomial is justified because n is large and exact calculations are too tedious O C Using the Normal approximation to the binomial is justified because np 15 and n 1 p 85 O D All of the above
