Answer:
At least 75% of the data will reside in the range of $3.25 to $3.81.
Step-by-step explanation:
Chebyshev's theorem states that:
At least 75% of the values in a distribution lie within 2 standard deviations of the mean.
At least 89% of the values in a distribution lie within 3 standard deviations of the mean.
In this problem, we have that:
Mean = $3.53
Standard deviation = $0.14.
Using Chebyshev's Theorem, state the range in which at least 75% of the data will reside.
Within 2 standard deviations of the mean
So
From 3.53 - 2*0.14 = $3.25 to 3.53 + 2*0.14 = $3.81.
At least 75% of the data will reside in the range of $3.25 to $3.81.
