Answer:
9.1 mg/dL
Explanation:
A normal distribution is symmetrical, the area below the curve of negative Z-scores is equal to the area below the curve of positive Z-scores, Z measures the statistic observed and the parameter of the population.
And it is:
Z = (x - μ)/σ
where μ is the mean (9.5 mg/dL), x is the borderline, and σ is the standard deviation, which is 0.3 mg/dL.
The Z-score can be calculated in excel by the function =NORMSINV, and the factor will be the percente considered (10% = 0.1)
NORMSINV(0.1) = -1.28155
So,
-1.28155 = (x - 9.5)/0.3
x - 9.5 = -0.384465
x = 9.1 mg/dL
