A polling organization contacts 1735 teenagers who are 16 to 19 years of age and live in North America and asks whether or not they had driven a car on a highway recently. What is the population in the study? 0 A. Teenagers who are 16 to 19 years of age. 0 B. Teenagers who are 16 to 19 years of age and live in North America and have driven a car on a highway. 0 C. Teenagers who are 16 to 19 years of age and have driven a car on a highway. 0 D. Teenagers who are 16 to 19 years of age and live in North America. What is the sample in the study? 0 A. Teenagers who are 16 to 19 years of age and live in North America. 0 B. The 1735 teenagers who are 16 to 19 years of age and have driven a car on a highway. 0 C. Teenagers who are 16 to 19 years of age. 0 D. The 1735 teenagers who are 16 to 19 years of age and live in Norlh America. Aconcrete mix is designed to withstand 3000 pounds per square inch (psi) of pressure. The following data represent the strength of nine randomly selected casts (in psi), 3970, 4080, 3300, 3200, 2930, 3840, 4080, 4030, 3510 D Compute the mean, median and mode strength of the concrete (in psi). Compute the mean strength of the concrete Select the correct choice below and, if necessary, ll in the answer box to complete your choice O A- The mean strength of the concrete is psi of pressure. (Round to the nearest tenth as needed.) O B. The mean does not exist. Compute the median strength of the concrete. Select the correct choice below and, if necessary, ll in the answer box to complete your choice. O A- The median strength of the concrete is psi of pressure. (Round to the nearest tenth as needed.) O B. The median does not exist. Compute the mode strength of the concrete. Select the correct choice below and, if necessary, ll in the answer box to complete your choice. O A- The mode of the strengths of the concrete is psi of pressure. (Round to the nearest tenth as needed.) O B. The mode does not exist. An insurance company crashed four cars in succession a! 5 miles per hour. The cost of repair for each of the four crashes was $427, $461, $416, $230 121 . Compute the range, sample variance, and sample standard deviation cost of repair. The range is $ 52 = dollars2 (Round to the nearest whole number as needed) s=$ (Round to two decimal places as needed.) Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 3000 grams and a standard deviation of 900 grams while babies born after a gestation period of 40 weeks have a mean weight of 3400 grams and a standard deviation of 565 grams. If a 34-week gestation period baby weighs 2625 grams and a 40-week gestation period baby weighs 3025 grams, nd the corresponding z-scores. Which baby weighs less relative to the gestation period? Find the corresponding z-scores. Which baby weighs relatively less? Select the correct choice below and ll in the answer boxes to complete your choice. (Round to two decimal places as needed.) O A- The baby born in week 34 weighs relatively less since its z-score, , is larger than the z-score of for the baby born in week 40. O 3- The baby born in week 34 weighs relatively less since its zscore, , is smaller than the zscore of for the baby born in week 40. O C- The baby born in week 40 weighs relatively less since its z-score, , is larger than the z-score of for the baby born in week 34. O D- The baby bom in week 40 weighs relatively less since its z-score, , is smaller than the z-score of for the baby born in week 34' The accompanying data represent the miles per gallon of a random sample of cars with a three-cylinder. 1.0 liter engine. (3) Compute the z-score corresponding to the individual who obtained 40.1 miles per gallon. Interpret this result. (b) Determine the quartiles. (c) Compute and interpret the interquartile range, IQR.
