A. 16%

Step-by-step explanation:

The zscore is used to solve problems of normally distributed samples.

This score indicates the percentage of a certain measure. It can be found looking at the z table.

Z = 1 has a pvalue 0.8413. So it is in the highest 1-0.8413 = 0.1587 = 16% percent of firms in the industry.

The correct answer is

Vlad1618 [11]

x - 3.5 = 8.5     Convert the improper fraction to a decimal number.

x = 12                Add 3.5 to both sides.
