Extracted text: 4. Making Chocolates-At the Sterling Chocolate Factory, a particular machine on the chocolates assembly line fails to insert the correct cream filling approximately 1.2% of the time. Chocolates without the correct filling cannot be processed into boxes of chocolates for shipping. a) Find the mean and standard deviation for the number of incorrectly filled chocolates per 10,000 made on the assembly line. b) In a particular batch of 10,000 chocolates, would 400 incorrectly filled chocolates be unusually low or unusually high?
