X = {68, 51, 75, 78, 94, 35}

Mean = (68+51+75+78+94+35)/6 = 66.8

|68-66.8| = 1.2

|51-66.8| = 15.8

|75-66.8| = 8.2

|78-66.8| = 11.2

|94-66.8| = 27.2

|35-66.8| = 31.8

Sum of Absolute Deviations = 1.2 + 15.8 + 8.2 + 11.2 + 27.2 + 31.8 = 95.4

Therefore, the sum of the absolute deviations is 95.4. Answer: 95.4
