Question

Based on the sample results what percent of the population prefers reading a hard copy? Digital copy:4 Hard copy:21 n=25 (A)-about 50% (B)-about 16% C-about 84% (D)-about 21%

Answer 1

the answer is c

Answer 2

C-about 84%

Explanation:

We are given that,

Total number of population, n = 25

Number of people who prefer to read a digital copy = 4

Number of people who prefer to read a hard copy = 21

It is required to find out the percent of population who prefer to read hard copy.

So, we have,

Percent of population preferring hard copy =
`(HardCopy)/(Total)* 100`

i.e. Percent of population preferring hard copy =
`(21)/(25)* 100`

i.e. Percent of population preferring hard copy = 0.84 × 100 = 84%

Thus, the percent of population who prefers to read a hard copy are about 84%.
