According to the approximation formula for the standard deviation of R in the Wald-Wolfowitz runs test: σR= √{ [(2n1n2)/(n1 + n2)(n1+n2-1)] } where n1 and n2 are the numbers of runs of 1's and runs of 0's, respectively. Substituting n₁ = 10 and n₂ = 10 into the formula: σR= √{ [(2×10×10)/(10 + 10)(10+10-1)] } = √{ [(200/19)]} = 3.498 Therefore, the best choice for the standard deviation of R is σ_R = 11ea8309_a9dd_053e_b223_1b1723e50178_TB6618_11.
