The distance is 12.041594578792295. Round to 12.0
Answer:
Option A - 4.91
Step-by-step explanation:
The formula for theoretical standard deviation of uniform distribution is;
σ = √{(b-a)^2}/12
Now from the question, b = 38 minutes and a= 21 minutes
Therefore, σ = √{(38-21)^2}/12
= √{17^2}/12 = √289/12 = 4.907 which is approximately 4.91
