An Olympic diver received the following scores: 4, 2, 5, 1. The standard deviation of her scores is in which of the following ranges?
Choose one:
A) 2.01 to 2.99 B) 4.01 to 4.99 C) 1.01 to 1.99 D) 3.01 to 3.99 E) 5.01 to 5.99
4+2+5+1/4=3   ∣4−3∣^2 =1^2 = 1   ∣2−3∣^2 =1^2 = 1   ∣5−3∣^2 =2^2 = 4   ∣1−3∣^2 =2^2 = 4   sqrt 10/4 =1.58   Answer : 1.01 to 1.99
