Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 800
Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2700 grams and a standard deviation of 800 grams while babies born aer a gestation period of 40 weeks have a mean weight of 2900 grams and a standard deviation of 400 grams. If a 34-week gestation period baby weighs 2925 grams and a 41 -week gestation period baby weighs 3125 grams, nd the corresponding zscores. Which baby weighs more relative to the gestation period? Find the corresponding zscores. Which baby weighs relatively more? Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) O A- The baby born in week 41 weighs relatively more since its z-score, , is smaller than the z-score of for the baby born in week 34. O B- The baby born in week 34 weighs relatively more since its z-score, , is smaller than the zscore of for the baby born in week 41. O C. The baby born in week 41 weighs relatively more since its z-score, , is larger than the z-score of for the baby born in week 34. O D- The baby born in week 34 weighs relatively more since its z-score, , is larger than the 2-score of for the baby born in week 41. In a certain city, the average 20- to 29-year old man is 69.8 inches tall, with a standard deviation of 3.0 inches, while the average 20- to 29-year old woman is 54.1 inches tall, with a standard deviation of 3.9 inches. Who is relatively taller, a 75-inch man or a 70-inch woman? Find the corresponding z-scores. Who is relatively taller, a 75-inch man or a 70-inch woman? Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) O A- The z-score for the man, , is smaller than the z-score for the woman, , so he is relatively taller. O B- The z-score for the woman, , is smaller than the z-score for the man, , so she is relatively taller. O C. The z-score for the man, , is larger than the z-score for the woman, , so he is relatively taller. O D- The z-score for the woman, , is larger than the zscore for the man, , so she is relatively taller. A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 2 standard deviations from the mean. The quality-control engineer knows that the bolts coming off the assembly line have mean length of 15 cm with a standard deviation of 0.10 cm. For what lengths will a bolt be destroyed? . . . Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to one decimal place as needed.) O A. A bolt will be destroyed if the length is less than cm. O B. A bolt will be destroyed if the length is greater than cm. O C. A bolt will be destroyed if the length is less than cm or greater than cm. O D. A bolt will be destroyed if the length is between cm and cm.The weight of an organ in adult males has a bellshaped distribution with a mean of 320 grams and a standard deviation of 30 grams. Use the empirical rule to determine the following. (a) About 68% of organs will be between what weights? b) What percentage of organs weighs between 230 grams and 410 grams? ( (c) What percentage of organs weighs less than 230 grams or more than 410 grams? (d) What percentage of organs weighs between 260 grams and 350 grams
