Estimate the number of people who are not interested in listening to pop music at the club.

• A. 456
• B. 156
• C. 444
• D. 300

Answer 1

The correct option is A 456

In the given sample,

Here,
Sample size = 24 + 26 + 50 = 100

Number of people who prefer pop = 24

Percentage of people who prefer pop:
$=\frac{24}{100}\times 100\%=24\%$

$\therefore$ Percentage of people who doesnot prefer pop = (100 - 24)% = 76%

Total number of people who doesn't prefer pop:
$=\frac{76}{100}\times 600=76\times 6=456$

$\therefore$Total number of of people not interested in listening to pop at the club are 456.
