Question 2. There is a type of candy such that the quantity of sugar X (measured in grams) in a randomly-selected piece of candy is normally distributed, with expected value u ten pieces of this candy on Halloween night. We are interested in calculating the probability that Hector consumed more than 200 grams of sugar, accurately. Which of the following is NOT true? = 22 and variance o? = 8. Suppose that Hector eats (a) We can not calculate the exact probability because n is not large enough (b) The expected amount of sugar consumed is 220 (c) The probability we are interested in is very close to 0.987 (d) 68% is the probability that Hector will be within one standard deviation of the expected total amount of sugar consumed.
