A researcher wishes to estimate the average blood alcohol concentration (BAC) for drivers involved in fatal accidents who are found to have positive BAC values. He randomly selects records from 60 such drivers in 2009 and determines the sample mean BAC to be 0.15 gIdL with a standard deviation of 0.060 gIdL. Complete parts (a) through (d) below. quuucmmua w: wuauuvuug a uuuuucuw numvm. A. The sample size is likely greater than 10% of the population. 3' B. The sample size is likely less than 5% of the population. C. The sample size is likely greater than 5% of the population. 0. The sample size is likely less than 10% of the population. (c) Determine and interpret a 90% condence interval for the mean BAC in fatal crashes in which the driver had a positive BAC. Select the correct choice below and ll in the answer boxes to complete your choice. (Use ascending order. Round to three decimal places as needed.) O A- There is a % probability that the population mean BAC is between and for drivers involved in fatal accidents who have a positive BAC value. O B- The researcher is % condent that the population mean BAC is not between D and D for drivers involved in fatal accidents who have a positive BAC value. O c- The researcher is % condent that the population mean BAC is between and for drivers involved in fatal accidents who have a positive BAC value
