Question

PLEASE ROUND ALL FINAL ANSWERS TO 3 DECIMAL PLACES :) The blood alcohol concentrations of a sample of drivers involved in fatal crashes and then convicted with jail sentences are given below (based on data from the US Department of Justice): 0.27, 0.17, 0.17, 0.16, 0.13, 0.24, 0.29, 0.24, 0.14, 0.16, 0.12, 0.16, 0.21, 0.17, 0.18 a. Find the mean b. Find the median c. Find the mode(s) d. Given that current state laws prohibit driving with levels that are higher than 0.08 or 0.10, does it appear that the levels above are significantly higher than the maximum that is allowed by law? Why or why not?

Explanation / Answer

i just wrote my answer what i exactly know :) a) mean= sum of all values given/no. of values= 2.81/15= .187 b) median is the middle value. so i'll have to rewrite in order 0.12, 0.13, 0.14, 0.16, 0.16, 0.16, 0.17, 0.17, 0.17, 0.18, 0.21, 0.24, 0.24, 0.27, 0.29 there are 15 numbers in the list so the middle one will be (15+1)/2= 8th number here the 8th number is 0.17. so, the median is 0.17 c)mode is the number that is repeated more often than any other, but here 0.16 and 0.17 are repeated 3 times each. so the modes are 0.16 & 0.17. d) sorry i don't know about this question...
