Answer:
[ 250 , 282 ]
Step-by-step explanation:
A Normal Distribution N ( 0,1)
We know one of the characteristics of a normal distribution is the symmetry and the fact that in the interval of
μ₀ - σ  and  μ₀ + σ  are found the 95.5 % of all values
In our case we have μ₀ = 266  and the standard deviation  σ = 16
So   μ₀ - σ   ⇒  266 - 16  = 250  the lowest value for the interval and
    μ₀ + σ   ⇒  266 + 16 = 282  the highest value for the interval
The interval  with 95.5 % of all values is
[ 250 , 282 ]
