Find the range, variance, and standard deviation for each of the two samples, then compare the two sets of results. When investigating times required for drive-through service, the following results (in seconds] were obtained. Restaurant A| 120 | 67 59 97 124 65 72 96 Restaurant B 115 126 49 56 95 76 78 95 Restaurant A: 57 sec; 493.98 sec : 22.23 sec A Restaurant B: 77 sec; 727.98 sec?: 26.98 sec There is more variation in the times for restaurant B Restaurant A: 57 sec; 493.98 sec : 22.23 sec B Restaurant B: 56 sec; 727.98 sec ; 32.89 sec There is more variation in the times for restaurant B. Restaurant A: 57 sec; 793.98 sec : 28.18 sec C Restaurant 6: 77 sec; 727.98 sec ; 26.98 sec There is more variation in the times for restaurant A. Restaurant A: 75 sec; 493.98 sec : 22.23 sec Restaurant B: 70 sec; 727.98 sec : 26.98 sec There is more variation in the times for restaurant B
