The unit ton, or metric ton, is a non-SI unit but commonly used in the United States. It is both approved by the NIST and the U.S National Institute of Standards and Technology. The equivalence is, 1 metric ton is equal to 1,000 kilograms. So, a metric ton is a thousand times bigger than a kilogram.
Answer:
The correct answer is - 97.74%.
Step-by-step explanation:
Given:
sample mean = 281
Std Dev = 47 ==> Sample
Std Dev (s) = std dev/sqrt(n) = 6.0677
Solution:
Find : P( x > 268 )
z = ( x - u )/s = ( 268 - 281 )/6.0677
= -1.9558
then, P( x > 270) = P( Z > -1.9558)
= P( Z <1.9558)
= 0.9747
change into percentage:
= 97.471%
Answer:
x=b/a
