Answer:

The description for the given question is described in the explanation section below.

Step-by-step explanation:

The given values are:

Number of non-pierced samples = 352

Total number of samples = 1000

(1)...

Now,

Number \ of \ percentage \ of \ the \ sample \ is \ not \ pierced,

=\frac{number \ of \ non-pierced \ sample}{total \ number \ of \ samples}\times 100

On putting the values in the above formula, we get

=\frac{352}{1000}\times 100

=35.2 %

(2)...

Expected numbers of unpierced females are = 64
