The formula for the standard error is this:
σM = σ / √N
where
σM is the standard error
σ is the standard deviation
N is the number of samples
So,
σM = 0.45 / √50
σM = 0.0636 or 6.36%
The standard error is 0.0636
1.Choice 4: 10
2. Choice 1: Add 5.2 to both sides if the equation.
Answer: (3/10) in = (7/8) mi
1 in = (7/8) mi ÷ (3/10)
= 7/8 * (10/3) = 70/24
1 in = (70/24) mi
It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.
