Find sd. Consider the set of differences between two dependent sets: 84, 85, 83, 63, 61, 100, 98. Round to the nearest tenth.
A) 15.3
B) 16.2
C) 15.7
D) 13.1

To find the standard deviation, first calculate the mean of the set: (84 + 85 + 83 + 63 + 61 + 100 + 98) / 7 = 82.0. Then, find the squared differences from the mean, sum them, divide by the number of values, and take the square root: sqrt(((84-82)^2 + (85-82)^2 + (83-82)^2 + (63-82)^2 + (61-82)^2 + (100-82)^2 + (98-82)^2) / 7) = 15.3.
