Consider a difference of \( 20 \% \) between two values of a standard deviation to be significant. How does this computed value compare with the given standard deviaton, \( 11.1 ? \) A. The computed value is significantly greater than the given value. B. The computed value is not significantly different from the given value. C. The computed value is significantly less than the given value.
