Select one: a. 0 b. 0.25 " c. 0.5 " d. 0.75 e. 1.0 What is the probability that a person selected at random from the population would have an IQ of more than 100? IQ is normally distributed with u = 100 and o = 15. Select one: a. 0 b. 0.25 " c. 0.5 d. 0.75 e. 1.0 The weights of 100 g packets of potato chips are actually not all equal to 100g. Their weights are distributed normally with a mean of 100 g and a variance of 1.44 (=1.22). What is the probability that a randomly selected packet is more than 1% below the correct weight? Give your answer to 4 significant figures. The weights of 100 g packets of potato chips are actually not all equal to 100g. Their weights are distributed normally with a mean of 100 g and a variance of 1.44 (=1.22). What is the probability that a randomly selected packet is more than 2% over the correct weight? Give your answer to 4 significant figures. The shaded area in the graph below is 0.065.
