3 The distribution of the weights of cereal in boxes of a specific brand of cereal is approximately normally distributed with mean 13 ounces and standard deviation 0.12 ounce. Complete parts (a) and (b) below. CHILE a. Explain why it would be unwise for the cereal company to advertise that each box contains 13 ounces of cereal. OA. Only half of the boxes of cereal would have exactly 13 ounces of cereal. OB. Less than half of the boxes of cereal would have at least 13 ounces of cereal. OC. More than half of the boxes of cereal would have at least 13 ounces of cereal. O D. Only half of the boxes of cereal would have at least 13 ounces of cereal. b. What should the company advertise the weight of the cereal in each box to be so that 99% of the boxes contain at least that much cereal? The company should advertise the weight of the cereal in each box to be 12.6 ounces. (Round to one decimal place as needed.) Time Remaining: 00:05:44 Next For students who graduated from high school in 2013, their scores on a standardized math test are approximately normally distributed with a mean of 505 points and a standard = deviation of 121 points. Complete parts (a) through (c) below. OA. Yes. The student's score is unusual. The associated z-score is OB. Yes. The student's score is unusual. The associated z-score is OC. No. The student's score is not unusual. The associated z-score is OD. No. The student's score is not unusual. The associated z-score is THR which is greater than the positive z-score required to determine whether an observation is unusual. which is less than the positive z-score required to determine whether an observation is unusual. .96 which is less than the positive z-score required to determine whether an observation is unusual. which is greater than the positive z-score required to determine whether an observation is unusual. b. A student who graduated from high school in 2013 scored 787 points on a standardized math test. Is that an unusual score? Explain. Select the correct choice below and fill in the answer box to complete your choice. (Round to two decimal places as needed.) OA. Yes. The student's score is unusual. The associated z-score is OB. No. The student's score is not unusual. The associated z-score is OC. No. The student's score is not unusual. The associated z-score is OD. Yes. The student's score is unusual. The associated z-score is 99 which is greater than the positive z-score required to determine whether an observation is unusual. which is less than the positive z-score required to determine whether an observation is unusual. which is greater than the positive z-score required to determine whether an observation is unusual. 99 which is less than the positive z-score required to determine whether an observation is unusual. c. For students who graduated from high school in 2013, find the cutoff for unusually high scores on a standardized math test. cording 21.04 PM Condo ead.xlsx cording 23.58 PM (a) throu (c) below. UB.
