We have data which gives the speed of a vehicle at the time of accident for accidents that happened on 4 highways. The data are saved in R in variables z1,22,z3 4. respectively. Beiow are the histograms for these variables: Histogram of xt Histogram of x2 O 50 100 150 200 250 0 0 100 110 120 130 Histogram of x3 Histogram of x4 97 98 9 100 101 102 40 60 80 100 120 140 160 For these four variables, the sample standard deviations are given below in an increasing order: 1.0 10.5 27.2 48.5. Identity the sample standard deviation of each variable. O *1- 48.5; sz9 - 10.5; a23 - 1.0; 4 - 27.2. O sz1 = 1.0; - 48.5; - 27.2, 24 - 10.5. O *1= 48.5 ; zg -1.0; za = 27.2; 4= 10.5. O 1 = 27.2; sz2 = 10.5; r3 - 1.0; 4 - 48.5. O 1- 10.5; sz2 - 1.0; z3 48.5, 4 - 27.2.
