Society of human resource management surveyed 347 human resource professionals.

Out of these, 73% responded that their companies checked the criminal background of all job applicants.

a.

The symbol % implies that a value is divided by 100.

Here, 73% of the 347 subjects surveyed are:

$$\begin{gathered} 73\%脳347=\frac{73}{100}脳347 \\ =253.31\text{subjects} \end{gathered}$$

Thus, 73% of 347 subjects is 253.31 subjects.

b.

The actual count should be a whole number, not a decimal number. Thus, the value 253.31 in part (a) cannot be the actual number of responses from the surveyed human resource professionals.

c.

The actual count can be obtained byrounding offthe decimal valuein step 2 to a whole number.

Thus, the actual count of professionals equivalent to 73% of survey responses is 253.

d.

It is known that 112 subjects in the survey were females.

The fraction of females in 347 subjects is $\frac{112}{347}$ .

The formula for determining percentage from the fraction is:

$\frac{112}{347}脳100=32.2767\%$

Thus, 32.2767% of the subjects surveyed are female.
