Answer:
Mean = 2
Standard deviation = 1.356
Step-by-step explanation:
We are given;
Probability of taxpayers that make mistakes when filling out forms: p = 0.08
Sample size; n = 25 
In binomial distribution;
Means is;
μ = np
Thus;
μ = 25 × 0.08 
μ = 2
Formula for standard deviation here is;
σ = √(np(1 - p)) 
σ = √(25 × 0.08(1 - 0.08))
σ = 1.356
